In Season 90 Warships for Boom Beach: War Strategy Game, overcome heavy defensive setups by prioritizing high burst-damage units, investing tech tree keys into offensive nodes, and using flares to guide forces along outer base lanes. Because defensive damage and building health scale higher than standard offensive units this season, attempting direct center assaults often results in total troop wipes before clearing a single engine room.
Tech Tree Investment Strategy
To maintain progress when defensive structures dominate matches, channel your tech tree keys into offensive survivability and structure disruption rather than building static defenses:
- Focus on Offensive Longevity: Upgrade nodes that provide troop health boosts or abilities that temporarily disable defensive buildings.
- Avoid Filler Defensive Nodes: Do not spend keys on low-impact defensive upgrades that fail to stop enemy raids.
- Target Engine Room Clears: Invest specifically to guarantee at least one engine room clear per battle, securing essential progress even when matches end in draws.
Combat Deployment and Tactical Pathing
When attacking heavily fortified layouts in Season 90, unit selection and pathing control determine whether your push reaches the primary targets.
| Strategic Need | Recommended Action | Tactical Outcome |
|---|---|---|
| High-HP Defense Scaling | Deploy high burst-damage units | Destroys priority targets before defenses complete full attack cycles |
| Splash Damage Overlap | Spread unit deployments across the beach | Prevents heavy area-of-effect damage from wiping entire troop clusters |
| Center-Loaded Heavy Defenses | Flare troops toward peripheral outer lanes | Trades assault speed for troop survival, allowing forces to reach engine rooms |
Avoid relying on sustained low-damage units or tight troop clusters. Direct your forces along outer perimeter paths with flares to bypass high-damage central defenses, prioritizing base clears and engine room destruction over clear speed.

This guide answered the exact question I had.
Can you add more details about base building in a future update?
I tried this today and it worked better than my old setup.
I wish I had read this before upgrading the wrong thing.
