Sentry is an upcoming wave defense FPS about alien hordes invading your spaceship

Indie developer Fireblade Software has announced a new game, Sentry, for the 2023 release. In Sentry, you are a defender trying to save a human ship while fleeing a defeated land, pursued by alien threats. When the aliens overtake your ship, you must fight in a dynamic defensive campaign that sees you hold the enemy from different ship systems. The combination of First-Person Shooter and Tower Defense can remind you of classic to something Sanctum.

The dynamic campaigns sound particularly interesting as you can do it alone or with a friend. “Do you want to decide to destroy a smaller force and prevent them from seizing a crucial subsystem? Or do you risk facing overwhelming odds that prevent a major enemy from advancing and blunt their main advance?”, The game description states. There is also a stated emphasis on intelligent enemies, which is a change from most of the action tower defense genre.
