Keep is a WW2-themed strategy shooter where you place flak turrets to defend your fortress, then jump into first-person mode to shoot down enemy planes. Switch between tactical planning and direct combat in a fast-paced blend of strategy and action
Keep
SteamKeep is a WW2-themed strategy shooter that blends tactical planning with intense first-person combat. Defend your fortress against coordinated assaults from the air, sea, and land using a unique possession mechanic that lets you shift seamlessly between strategic overview and direct control. Begin each encounter in an aerial view—build towers, assign turrets, and position your defences across the terrain. When the attack begins, possess any turret or emplacement and drop into first-person view to engage incoming threats head-on. Whether it's aircraft, ships, or advancing ground units, you'll need to switch perspectives often to stay ahead of the battle. Once an area is secured, return to the tactical layer to reassess, rearm, and reposition. The game flows constantly between high-level strategy and close-quarters combat, rewarding both smart planning and sharp aim.
Key Features:
● Hybrid Gameplay – A seamless mix of real-time strategy and first-person shooting.
● Possession Mechanic – Construct towers, assign weapons, then take control in FPS mode.
● Multi-Front Combat – Defend against aerial, naval, and land-based enemies.
● Dynamic Perspective Switching – Jump between tactical overview and immersive turret combat at any time.
● Fortress Evolution – Upgrade defences and adapt your layout as threats intensify.
● Atmospheric WW2 Setting – Realistic environments and sound design immerse you in the conflict.
Think fast, aim true, and hold the line. Keep is where strategy meets survival.
