Resident Evil Survival Unit How to Progress Faster: Base Building and Upgrade Priorities
Progressing quickly in Resident Evil Survival Unit is all about making smart building decisions, resource management, and focusing upgrades on what matters most. A well-optimized base ensures steady growth, powerful troop deployment, and long-term dominance in the campaign and PvE events.
Prioritize Your Mansion: The Heart of Progress
The Mansion serves as your HQ and sets the maximum upgrade level for all other buildings. Raising your Mansion level should always be your top priority, as every major feature, new building, and research path is gated behind your Mansion’s upgrade progression.
| Building | Function | Priority Reason |
|---|---|---|
| Mansion | Unlocks all features | Sets the pace for every upgrade |
| Alliance Center | Social + speed help | Reduces build/research timers |
| Resource | Food, wood, materials | Needed for all upgrades |
| Training | Troop growth | Keeps your squads competitive |
| Research Lab | Speed, stats, boosts | Long-term power scaling |
Upgrade Order for Maximum Efficiency
- Mansion – Always keep this at the highest level possible.
- Alliance Center – Closely follow Mansion level to increase help from other players (reducing wait times).
- Resource buildings (Farm, Lumber Mill, Fuel Facility, Material Depot) – Upgrade evenly for a balanced resource flow.
- Barracks, Shooting Range, Garage – Upgrade troop training buildings together so you can unlock higher-tier troops as soon as possible.
- Research Lab – Boost this when possible to speed up all future research and combat upgrades.
Power Up Your Heroes Early
Invest in raising the levels and stars of Epic and Legendary heroes only. Avoid wasting resources on lower-tier or rarely used units, as resources are limited. Save Premium Flare Guns for Epic banners to get the best characters, and spend EXP, hero shards, and skill upgrades on those with the highest long-term potential.
Use Speedups and Diamonds Wisely
- Only use speedups and Diamonds on Mansion upgrades, key building completions, or critical research. Don’t spend them on minor marches or low-tier upgrades.
- Free daily draws and alliance operation events are the best way to accumulate speed boosters and avoid wasting premium currency.
Check Troop Health and Defend
Injured or infected troops slow down your base and can even affect morale and economic growth. Heal survivors quickly at the Hospital and watch for alliance rallies and defense bonuses via the Alliance Center.
Event Participation for Rapid Progress
Events are your fastest way to extra resources, rare items, and premium upgrades. Always check the in-game event tab and participate in time-limited activities to collect major rewards for your base.
