In the grid-based, post-apocalyptic strategy world of Tiles Survive, building a powerful settlement and commanding elite hero armies requires more than just rapid tapping or base construction. Long-term account progression operates as a compounding engine. At the absolute center of this engine is tiles survive research. Research conducted inside your Research Lab is the only core progression system in the game that yields permanent, multiplicative bonuses that last for the entire lifespan of your account. Whether boosting construction speed, enhancing troop lethality, or unlocking elite unit tiers, every technology unlocked reduces future time and resource bottlenecks.
This comprehensive tiles survive research guide provides a complete strategic breakdown of the game’s technology ecosystem. From establishing your initial development queue to navigating complex late-game technology trees, optimizing Clash Medal spending, and timing your upgrades for maximum event points, this guide covers everything you need to master your settlement’s scientific advancement.
The Research Facility: Navigating the Tiles Survive Research Center
All technological advancement in Tiles Survive takes place within the Research Lab (frequently referred to by the community as the tiles survive research center). The Research Lab acts as the primary hub where players invest resources, time, and premium currencies like Clash Medals to upgrade passive settlement and military attributes.
Infrastructure Dependencies and Gating
Your Research Lab cannot be upgraded in isolation. Progression across your entire settlement is bound by your Power Plant level. The Power Plant serves as the structural backbone of your base; any facility upgrade beyond specific level thresholds requires the Power Plant to match that level first. If your Power Plant lags behind, your Laboratory level caps, halting your access to higher-tier technologies, advanced troop prerequisites, and late-game military trees.

Queue Management: Managing Research Capacity
A primary concern for competitive players is optimizing research queue uptime. Players often look for ways to unlock a tiles survive second research slot or secure tiles survive extra research queues to run multiple technology projects simultaneously.
Based on official game mechanics, primary technology progression runs through a single main active Laboratory queue. While seasonal events occasionally introduce temporary bonuses—such as the free seasonal construction slot introduced in version 2.4.0—there is no permanent secondary Laboratory building for a tiles survive second research queue. Because of this single-queue structure, managing your main research queue efficiently is paramount. Rather than splitting focus across multiple simultaneous projects, efficiency is achieved by maximizing percentage-based research speed buffs, leveraging alliance help timers, utilizing the Resource Bot, and deploying targeted research speedups.
To get the most out of your queue without wasting resources:
- Prioritize Research Speed Tech Early: Percentage-based reductions shorten every subsequent project placed in the queue.
- Maximize Alliance Helps: Upgrading structures like the Communications Center / Cosmos Outpost increases the number of alliance helps you can receive, cutting significant time off long research projects.
- Capitalize on Event Windows: Save long-duration tech upgrades for designated event days to double-dip on progression and leaderboard rewards.
Determining the Tiles Survive Research Priority
Establishing a clear tiles survive research priority during the first 30 days of an account dictates how fast your power compounds across subsequent months. Rushing directly into advanced player-versus-player (PvP) combat trees early in a server’s lifecycle is a common pitfall. A combat-focused account that neglects economic and PvE development quickly grinds against severe resource and speedup bottlenecks.
[Phase 1: Economy & Speed] ──> [Phase 2: PvE Engine] ──> [Phase 3: Versus & Special Forces]
Phase 1: Development and Economy Tech Trees
Your immediate Day 1 priority must focus on economic sustainability and speed multipliers:
- Construction Speed Research: Maxing construction speed technologies first provides immediate returns. A 25% construction speed bonus by week three significantly accelerates your Power Plant milestones, reducing the real-time cost of all future base upgrades.
- Research Speed Research: Research speed is the ultimate meta-stat. Each percentage point added reduces the time required for every future node across all technology trees, accelerating your overall progression curve.
- March Speed & Load Capacity: These twin development technologies work in tandem. Faster march speeds reduce downtime on the world map, while increased load capacity allows your gathering marches to bring back significantly more resources per trip.
- Resource Generation Rates: Flat bonuses to Farm, Lumberyard, Steel Plant, and Oil Refinery output ensure your settlement maintains a steady baseline income to fund continuous training and construction.
Phase 2: PvE Efficiency and Resource Loops
Once your economic foundation is secure, shift your focus toward PvE efficiency trees—specifically Infected Conquest. High PvE efficiency generates a steady stream of hero experience, resource crates, and speedups, effectively funding your late-game combat trees through map activity.
Phase 3: Survival, Defense, and Advanced Military
After establishing economic and PvE efficiency, transition into combat-focused survival trees:
- Troop Death Reduction: Converts potential casualties into wounded units, drastically reducing the resource cost of retraining armies after PvP engagements.
- Garrison Capacity & Utility: Expands the maximum number of troops your settlement can hold, increasing your defensive survivability and rally participation limits.
Deep Dive: Key Tiles Survive Research Trees
The game features several specialized branches within every tiles survive research tree. Understanding the specific benefits of each branch allows commanders to invest their speedups and Clash Medals where they yield the highest returns.
+-----------------------------------------------------------------------------------+
| TILES SURVIVE RESEARCH TREES |
+------------------+-------------------+--------------------+-----------------------+
| INFECTED CONQUEST| ALLIANCE DUEL | SPECIAL FORCES | DOOMSDAY EXPRESS |
+------------------+-------------------+--------------------+-----------------------+
| • EXP & Speedups | • Vs Points Buffs | • T10 Unit Unlock | • Logistics Buffs |
| • Crate Drops | • Daily Chest 4-9 | • Army March Cap | • Behemoth Cell Drops |
| • Versus Medals | • Medal-Only Tech | • Medal + Res Cost | • Super Truck Tech |
+------------------+-------------------+--------------------+-----------------------+
1. Tiles Survive Infected Conquest Research
Investing in tiles survive infected conquest research turns world map threats into a primary source of account growth. Rather than mindlessly burning stamina, completing this tree ensures that every map engagement yields maximum returns.
Key technologies within this branch include:
- Infected Fiend Conquest – EXP Bonus: Significantly scales the hero and commander experience points earned from defeating elite map targets.
- Infected Fiend Conquest – Speedup Items: Increases the volume and quality of construction and research speedups dropped by elite target rallies.
- Infected Conquest – Random Crate: Improves drop rates and crate contents obtained from world map activities.
- Versus Medal Generation Chests: Unlocks high-tier chests that grant direct Clash Medals alongside speedup items.
The Rally Leader Restriction Rule (Version 2.5.500 Patch)
Commanders must pay close attention to system mechanics introduced in update 2.5.500. FunPlus updated the descriptions and functionality of both Infected Fiend Conquest – EXP Bonus and Infected Fiend Conquest – Speedup Items to enforce strict rally rules:
- Rally Leaders Only: Bonuses from EXP Bonus and Speedup Items apply strictly to the Rally leader who initiates and successfully defeats an Infected Fiend.
- Rally Participants: Players who assist or join a rally do not receive these research-scaled bonus drops.
To optimize alliance progression, active members should rotate rally leadership so all damage-dealers can trigger their high-tier research multipliers.
2. Alliance Duel (VS) Tech Tree and Clash Medal Economy
The Alliance Duel research category is unique because it requires only Clash Medals—rather than standard wood, food, or stone—to complete its nodes. Clash Medals are earned through weekly Alliance Duel matchups, seasonal faction events (like Copper Clash and Oil Clash), and deep Infected Conquest drops.
This tree provides two essential account upgrades:
- Unlocking Daily Chest Tiers: Standard accounts are structurally capped at opening only the first three daily Alliance Duel chests. Upgrading the initial nodes in this tree unlocks chests 4 through 6, while maxing out the final nodes fully unlocks daily chests 7 through 9, which contain premium skill manuals, venom cells, and Clash Medals.
- Automated Point Multipliers: Mid-tree upgrades grant massive point multipliers (such as a 50% boost to points earned during troop training or research days). Maxing this tree ensures you reach the 5-million-point daily threshold with minimal effort.
3. Tiles Survive Special Forces Research
Once daily event chests 7 through 9 are unlocked in the Alliance Duel tree, your secondary medal focus must shift to tiles survive special forces research. Unlike the VS tree, Special Forces research tasks require massive quantities of standard resources alongside thousands of Clash Medals.
[VS Tech: Chests 7-9 Unlocked] ──> [Shift Medals to Special Forces] ──> [Unlock T10 Troops (6,000+ Medals)]
Key features of Special Forces research include:
- Combat Stat Scaling: Direct percentage increases to total army march capacity, troop attack, defense, and training speeds.
- Unlocking T10 (Level 10) Troops: Special Forces is the only technology tree in the game that unlocks Tier 10 troops.
- High Medal Costs: Unlocking T10 units represents a major late-game milestone. The final node requirement alone demands a staggering 6,000 Clash Medals, with preceding nodes costing between 3,000 and 9,000 medals.
4. Tiles Survive Doomsday Express Research
Advancing your tiles survive doomsday express research improves settlement-wide shipment and transport logistics. Upgrading this tree increases the frequency of rare Behemoth Cell drops and Behemoth experience points, which are required to level up active tactical Behemoths like the Gryphon.
Following update 2.4.700, unlocking “Super Truck Tech” within this tree grants access to Mega Mode:
- Mega Refresh: Allows chiefs to instantly refresh truck queues to guarantee S-class shipment trucks.
- Mega Shipment: Automatically assigns defensive formations and dispatches trucks instantly, maximizing daily reward efficiency.
5. Might of the Ocean and Faction Tech Trees
Introduced in version 2.4.600 under Settlement Techs, the Might of the Ocean research tree provides specialized Power and combat stat bonuses dedicated exclusively to Mariner-faction heroes. If your core battle formations rely on Mariner heroes (such as Tara or specialized Mariner builds), allocating research time here provides faction-aligned stat multipliers that general combat trees cannot match.
Identifying the Tiles Survive Best Research Path
Choosing the tiles survive best research path depends on your account age, VIP level, and alliance focus. The table below outlines recommended research priorities across different stages of account development:
| Account Stage | Primary Research Focus | Key Target Technologies | Core Strategic Impact |
|---|---|---|---|
| Early Game (Days 1–30) | Development & Economy | Construction Speed, Research Speed, March Speed, Load Capacity | Establishes base infrastructure, reduces upgrade timers, and prevents resource starvation. |
| Mid Game (Days 31–90) | PvE & Event Scaling | Infected Conquest (EXP Bonus, Speedup Items), Alliance Duel Chests 4–6 | Generates a continuous stream of speedups and unlocks daily event reward tiers. |
| Late Game (Days 90+) | Elite Units & PvP | Special Forces (T10 Troops), Max VS Chests 7–9, Might of the Ocean, Troop Death Reduction | Unlocks max unit tiers, maximizes march capacity, and reduces PvP hospital losses. |
Timing and Optimization: Wednesday “Tech Day” Scheduling
The single most costly error a commander can make is completing research projects immediately as resources become available. Realizing the full value of your research requires strict calendar discipline.
[Hold Speedups & Medals] ──> [Wait for Wednesday Tech Day] ──> [Unleash Upgrades] ──> [Claim 5M+ Event Rewards]
The Wednesday Double-Whammy
The weekly Alliance Duel operates on a fixed daily schedule. Wednesday (Day 3) is designated as Tech Research Day. On this day, players score massive event points for:
- Completing technology upgrades in the Research Lab.
- Consuming general and research speedups.
- Spending Clash Medals on Alliance Duel or Special Forces trees.
By holding completed upgrades and stockpiling research speedups and Clash Medals until Wednesday, you execute a highly lucrative “double-whammy”. You gain the permanent passive stats from the technology itself, while simultaneously generating millions of Alliance Duel points. Reaching the 5-million-point milestone returns fresh Clash Medals, gems, and speedups directly to your inventory, creating a self-sustaining growth cycle.
Summary Command Checklist
To maintain a top-tier research trajectory in Tiles Survive, keep these core principles in mind:
- Power Plant Alignment: Always keep your Power Plant upgraded ahead of your Laboratory to avoid structural level caps.
- Economy Before War: Complete Construction and Research Speed nodes before heavy investment in military trees.
- Infected Conquest Priority: Maximize EXP Bonus and Speedup Items early, and ensure active members rotate rally leadership to trigger leader-only bonuses.
- Clash Medal Discipline: Spend medals in the Alliance Duel tree first to unlock daily chests 7 through 9, then transition into Special Forces to push for T10 troops.
- Wednesday Execution: Hold research speedups and Clash Medals for Wednesday’s Tech Research Day to maximize weekly event payouts.
By aligning your Research Lab development with smart stamina allocation, event calendars, and alliance coordination, your settlement will build an unshakeable technological advantage across every season.
