What is SENTRY?

In this first-person shooter and tower defense campaign, you play a crew member awakened from stasis to protect a fleeing spaceship. Choose a route, then shoot boarding aliens, set traps and turrets, and use the environment to keep them from reaching the Core. Lost defenses change where you make your next stand rather than resetting a checkpoint. You can play alone or with an online co-op partner.

For you if...

+you like balancing quick shooting with defense planning
+you enjoy trying different equipment as you unlock it
+you want to defend a ship with an online partner

Not for you if...

−you want traps to do most of the fighting
−you prefer slow combat without waves of attackers
−you want a finished game rather than Early Access
