SENTRY

SENTRY throws you into the heart of a desperate struggle. As a lone defender aboard a besieged spaceship, you’ll face relentless waves of alien aggressors. In this first-person shooter, you’ll have to think strategically and act quickly to protect your ship. The enemy attacks various subsystems of the ship, trying to disable critical functions or gain access to new areas. You must prioritize targets, choosing between eliminating small threats and holding the front line against larger attacks. Every decision has weight, determining the course of the battle. Your main weapon is the ability to handle long-range weapons. However, victory depends not only on shooting. The game equips you with a powerful arsenal of traps and turrets. Place them in strategic locations to create screens, direct enemy movements, and unleash automatic firepower. When the situation gets dire, environmental destruction becomes your last resort.
