Sentry

SENTRY is a campaign action-defense game in which you protect a ship fleeing through space. Thawed from stasis as a member of the SENTRY Defense Program, you choose escape routes in the Navigator, where encounters with alien vessels are unavoidable. Enemies board and fight through the ship’s subsystems to destroy its Core, and you must keep the Core operational while seeking a way to escape.

Defend the ship

You fight with ranged weapons and can deploy traps and turrets to hold back aggressive, reactive enemies. You can also use environmental destruction: a well-timed shot can vent aliens into space, while closing a blast door can buy time to set up new defenses. Successful escapes call for a mix of combat skill and planning, and discovering and upgrading equipment can give you an edge.

A continuing campaign

Your choices and performance shape an ongoing fight for the ship’s survival rather than a series of one-off battles. If you fail to defend a level, the defeat changes the strategic situation in the Ship Overview and forces you to decide where to make your next stand; it does not send you back to replay a checkpoint. If your SENTRY falls, the program thaws another crew member to continue the fight. As long as a SENTRY survives and the Core remains operational, victory is still possible.

Campaign and co-op

The campaign can be played alone or with an online friend fighting alongside you in co-op.
