Just remember these key points first
- In the early phase, securing the Solar Power Plant and Airport first is the key to increasing your overall operating speed.
- From the mid phase onward, you need to manage both building points and enemy troop attrition at the same time.
- In the last 10 minutes, the Water Resource Center becomes the biggest comeback point.
- Blindly fighting all the time is weaker than understanding the score structure and winning through building control.
- The side that instantly picks up dropped temporary points and gathering-site score boxes has a clear advantage.
1. Entry Requirements
- Each alliance can form only one team.
- The team setup is 30 main members plus 10 backup members.
- The alliance leader or an R4 registers the team.
- You must join the alliance before registration closes.
- If your troops are marching or healing, you cannot enter.

2. How to Win
- You gain points by occupying buildings inside the Reservoir area.
- The alliance with more points at the end wins.
- Rewards are distributed based on team performance and individual points.
This mode is not just a simple combat event. It is a score battle built around building control, point management, and troop rotation.

3. Key Building Roles
The final core scoring building and the most important deciding point in the last 10 minutes.
Increases building occupation speed by 50%. Extremely important for early tempo control.
Reduces teleport cooldown by 50%. Makes a huge difference in rotation and central regroup speed.
Allows you to send infected units to enemy buildings and disrupt their building operation.
Provides +15% attack and +15% defense. Helps stabilize direct clashes.
Spawns score boxes that can be collected instantly. Fast pickup matters.
One more thing you must remember
If building occupation fails, accumulated temporary points drop onto the ground, and both sides can pick them up. That means the side that collects those points faster after a clash often creates the real score gap.

4. Team Role Assignment
To keep combat stable, it is better to divide participants into three or four groups. If everyone piles into one place, both building maintenance and rotation management start falling apart.
- Attack Team: weakens enemy power, forces clashes, and burns enemy troop strength
- Support Team: moves immediately where needed and flexibly supports both offense and defense
- Defense Team: maintains occupied buildings and secures stable points
- Collection Team: gathers dropped points after successful captures and clears gathering sites
The key is not “everyone fights.” It is clearly deciding who fights, who holds, and who collects points.

5. Phase-by-Phase Operation
Early Phase: Build the foundation first
- The defense team and support team should prioritize capturing the Solar Power Plant and the Airport.
- The attack team should start draining enemy troop strength from the beginning to break the enemy tempo.
- If the attack team runs low on troops, pull back, heal, and return instead of forcing fights.
In the early phase, securing operation-speed buffs matters more than kill count. The side that takes the Solar Power Plant and Airport first will have a much easier mid game.
Mid Phase: Building point control becomes the core
- Split the defense team into two groups.
- Group A manages the Solar Power Plant, Processing Center No. 2, and the Infected Holding Area.
- Group B manages the Airport, Processing Center No. 1, and the Tank Factory.
- The attack team keeps pressuring enemy troops to disrupt their building control.
- The support team rotates flexibly depending on building status and frontline pressure.
In the mid phase, direct fighting is less important than which side can hold its buildings more steadily. The alliance that keeps buildings longer usually controls the score flow.
Final 10 Minutes: Focus on the Water Resource Center
- Begin the full push to capture the Water Resource Center.
- Place teleports in a rotating pattern around the center to improve regroup speed.
- The attack team starts the first rally.
- The support team follows with chained rallies a few seconds apart.
- If the capture succeeds, the chance of a score reversal becomes very high.
Reservoir Raid is truly decided in the final 10 minutes. Even if you fall behind earlier, a strong combination of Water Resource Center control, follow-up rallies, and fast re-entry can still flip the match.

6. Extra Tips
- Focus on taking down the enemy’s strongest combat player first. It makes the whole frontline easier.
- Collect dropped points immediately whenever building occupation fails.
- Grab gathering-site score boxes as soon as they appear.
- Activate all buffs, gear, and skills before battle starts.
- Controlling the Airport greatly reduces teleport cooldown and makes the whole operation smoother.
- Prepare enough healing speedups in advance.
- If possible, use voice chat for real-time calls. It is much more stable.
Reservoir Raid is not a mode with one fixed answer based only on raw power. The most important part is choosing an operating style that matches your alliance strength, participation level, leadership structure, and player style.

Summary
Early game: secure operation-buff buildings. Mid game: hold points steadily. Late game: focus on the Water Resource Center. If you lock in those three core ideas, your Reservoir Raid win rate will clearly improve.
