The biggest installment of the award winning Sentinel sci-fi tower defense series now on PC!Take the fight to the alien homeworld and unleash a massive arsenal of weaponry. Get up close and personal on the battlefield in your power armor to execute devastating attacks and support your defenses! * An epic campaign across 20 levels.
The game features a fixed path system, where enemies follow predetermined routes to the player's base. Players must strategically place and upgrade various defensive turrets along these paths to eliminate the alien invaders.
The game offers over 20 unique turrets, including machine guns, missile launchers, and laser beams. Players can place these turrets and upgrade them to deal exponentially more damage. Careful tower placement and upgrade decisions are crucial to optimizing the defenses.
A unique aspect of the gameplay is the inclusion of a customizable and upgradable commander unit. This mobile unit can be equipped with abilities like jump jets, repair functions, and attack boosts. Players can strategically position the commander to support their tower defenses, making it a crucial part of the strategy.
The game introduces an interesting risk/reward mechanic through its "interest" system. Players earn interest on any unspent funds each round, incentivizing them to carefully manage their resources and avoid over-building. This creates a tension between investing heavily in defenses versus maintaining a healthy income stream.
In addition to the main campaign, the game offers endless modes for each map. These allow players to compete for high scores and continue playing their favorite levels indefinitely, adding to the game's replayability.
Between missions, players can customize their loadout of towers and commander abilities. Earning experience points allows them to unlock new turrets, upgrades, and commander skills, providing a sense of progression and flexibility in tailoring their strategies.
