THIS IS A WORK IN PROGRESS…WE WILL CONTINUE TO UPDATE WITH SCREENSHOTS.
If you’re trying to figure out whether your power is “good” for your Mansion level in Resident Evil: Survival Unit, welcome… because nobody tells you this stuff in-game. The Mansion is the absolute core of your entire account, and if it falls behind, everything else falls behind with it: troop tiers, research caps, march slots, building limits, you name it.
This guide gives you a practical, realistic benchmark of where your Combat Power should be at each Mansion, the requirements for each level and the amount of time. (Some of these will be slightly different depending on your alliance, research, and upgrades, but it will give you an idea)
level, plus the upgrade costs, bottlenecks, and the “uh oh, you’re falling behind” checkpoints. I’ll be extending this all the way up to Mansion 30 as new data comes in.
Why Your Mansion Level Matters More Than Anything Else
Your Mansion is the core of every single thing in your Resident Evil Survival Unit’s world. Everything is based off your mansion level. It is your account progression speed. Every major system unlocks behind a Mansion requirement, including new troop tiers and core research branches. If you get stuck because you leveled the wrong buildings, you can delay your progress by days.
So leveling smart matters. A lot.
This guide shows exactly what your account should look like at each step.

📦 Required Resources
🍖 Food: 3.1M
🌲 Lumber: 3.1M
⛓️ Iron: 630K
⛽ Fuel: 150K
⏳ Upgrade Time
Approx. 13.5 hours (about half a day)
🏗️ Prerequisite Buildings
✅ Alliance Center: Level 13
✅ Garage: Level 13
🏰 Mansion Level 14 – Expected Power ~2.0M–2.6M
By Mansion 14, players in active alliances average between 2.2M and 2.5M. If you’re below 2M, you are underbuilt in either research or troop count.
What your account should have by now:
Tier 4 troop unlock in progress
Gear crafting started
Research Lab never idle
At least one Barracks pushed hard for troop massing
If you’re below benchmark:
Hospital → Research → Barracks in that order.
🏰 Mansion Level 15 – Expected Power ~2.6M–3.2M
Based on your screenshots, most M15 players sit around 3.0M–3.3M, meaning mid-game pressure is officially kicking in.
Why this level matters:
Mansion 15 is the first point where players’ troop numbers make HUGE differences. A strong M15 will always beat a weak M17 if the troop counts differ enough.
🏰 Mansion Level 16 – Expected Power ~3.2M–4.0M
Your alliance screenshots show Mansion 16 players sitting between 3.4M and 3.8M, which is exactly where a healthy M16 should be.
What changes at M16:
Tier 4 becomes fully trainable
Research costs spike
Power jumps depend almost entirely on troop production
To stay on track:
Try to maintain continuous troop training — missing even one day slows your entire account.
🏰 Mansion Level 17 → 18 Upgrade
🛡️ Combat Power
Before: 276,600 After: 317,000 (estimated from +40,400 shown) Gain:+40,400
📊 Expected Player Power at Mansion 17
At M17, players begin to diverge based on gear, research, and hero development.
Below 4.0M → 🚩 Underpowered
4.2M–4.6M → ✅ Normal progression
4.8M+ → 🔥 Strong, optimized account
📦 Required Resources
12M Food
12M Lumber
2.5M Iron
620K Fuel
⏳ Upgrade Time
1d 12h 26m 52s
🏰 Mansion Level 18 → 19 Expected Power ~5.0M–6.2M
🛡️ Combat Power
Before: ~317,000 After (est.): ~362,000 Gain (est.):+45,000
Power gains start accelerating again here. Mansion upgrades matter less than systems (gear, heroes, research), but the raw CP jump is still meaningful.
📊 Expected Player Power at Mansion 18
By M18, account efficiency matters more than time played.
Below 4.8M → 🚩 Underpowered
5.0M–5.6M → ✅ Normal progression
5.8M+ → 🔥 Strong / optimized
Why the jump? M18 is where players who ignored gear, hero stars, or research start falling behind fast.
📦 Required Resources
15M Food
15M Lumber
3.1M Iron
780K Fuel
⏳ Upgrade Time
~2 days 6 hours
At this tier:
Speedups become mandatory
Alliance help matters a lot
Timers start pushing toward 3 days soon
🏗️ Required Buildings
➡️ Alliance Center Level 18
➡️ Shooting Range Level 18
🔴 M18 Progression Warning
At Mansion 18, buildings alone will not carry you.
High-impact focus areas:
🔹 Blue → Purple gear upgrades
🔹 Hero star levels & exclusive skills
🔹 Military / damage research
🔹 Troop tier quality over quantity
Players who keep “just upgrading buildings” typically stall here.
🏰 Mansion Level 19 → 20 – Expected Power ~6.0M–7.4M
🛡️ Combat Power
Before: ~374,000
After (actual): ~431,400
Gain: +57,400
This is a noticeable CP spike, but like M18, the real separation now comes from research depth, hero investment, and gear, not just the mansion itself.
📊 Expected Player Power at Mansion 19–20
At this stage, inefficiencies compound quickly.
Below 5.8M → 🚩 Underpowered
6.0M–6.6M → ✅ Normal progression
6.8M+ → 🔥 Strong / optimized
Why this tier matters: M19–20 is where players who skipped alliance tech, attacker research, or gear upgrades begin to fall permanently behind, even if they keep leveling the mansion.
📦 Required Resources (19 → 20)
21M Food
21M Lumber
4.3M Iron
1.0M Fuel
60K Rare Minerals
This is a big resource wall — alliance support, territory buffs, and timing donations start to matter more than grinding.
⏳ Upgrade Time
~2 days 19 hours (before helps / speedups)
At this tier:
Speedups are no longer optional
Alliance help saves hours, not minutes – If you are not part of an ACTIVE help maxing alliance.. Look to switch!!
Timers are now firmly in the 3-day range
🏗️ Required Buildings
➡️ Alliance Center Level 19 ➡️ Shooting Range Level 19
These prerequisites quietly gate progress and often catch players off guard if ignored earlier.
🏰 Mansion Level 20 → 21 — Expected Power ~6.8M–8.2M
🛡️ Combat Power
Before: ~431,800 After (actual): ~489,200 Gain:+57,400
This is a solid but predictable CP bump. At this tier, mansion upgrades no longer create meaningful separation on their own — real power now comes from research depth, hero stars, gear quality, and troop efficiency.
📊 Expected Player Power at Mansion 20–21
At this stage, weak foundations are no longer recoverable without deliberate correction.
Below 6.8M → 🚩 Underpowered
7.0M–7.6M → ✅ Normal progression
7.8M+ → 🔥 Strong / optimized
📦 Required Resources (20 → 21)
27M Food
27M Lumber
5.4M Iron
1.3M Fuel
This is a major resource wall.
At this tier:
Alliance territory buffs matter
Timed donations matter
Poor resource planning becomes painfully visible
Grinding alone is no longer efficient.
⏳ Upgrade Time
~3 days 14 hours (before alliance helps / speedups)
🏗️ Required Buildings
➡️ Alliance Center Level 20 ➡️ Barracks Level 20
These prerequisites quietly block progress and often force unplanned detours, especially for players who rushed earlier mansion levels.
🏰 Mansion Level 21 → 22 — Estimated Power ~7.6M–9.0M
🛡️ Combat Power
Before: ~489,200 After (estimated): ~547,000 Gain:~+57,000–58,000
The mansion CP gain continues its flat trend. At this tier, the building itself contributes less to real combat outcomes than research, heroes, gear, and troop efficiency.
📊 Expected Player Power at Mansion 21–22
Power gaps are now structural, not temporary.
Below 7.6M → 🚩 Underpowered
7.8M–8.4M → ✅ Normal progression
8.6M+ → 🔥 Strong / optimized
📦 Required Resources (21 → 22)
36M Food
36M Lumber
7.2M Iron
1.8M Fuel
This is a heavy escalation tier.
⏳ Upgrade Time
~4 days+ (before helps / speedups)
🏗️ Required Buildings
➡️ Alliance Center Level 21 ➡️ Garage Level 21
These prerequisites frequently cause delays for players who rushed mansion upgrades without keeping infrastructure aligned.
