How co-op works
Two online SENTRYs share a run-based escape campaign, bringing personal equipment while the host controls route and ship state. They place traps and turrets, fight boarding waves in first person, cover extra breach points, and bank individual unlocks between battles.
About this game
SENTRY drops you into the corridors of a besieged spaceship where alien invaders pour through the hull and only coordinated firepower and smart defenses stand between survival and extinction. This is true cooperative play, designed for players who want to work together laying traps, positioning turrets, and covering each other as they fight room to room.

The action blends first-person shooting with tower-defense strategy. You and your partner place automated defenses, trigger environmental hazards, and gun down anything that breaks through. Communication is critical as you carve an escape route through hostile space, balancing offense with resource management under constant pressure.
Online co-op lets you team up remotely to defend the ship. Every session demands quick callouts, shared situational awareness, and tactical coordination. If you enjoy high-stakes firefights wrapped around cooperative planning, SENTRY delivers intense, communication-heavy teamwork.
