This game doesn't have excellent graphics. It doesn't have quicktime events, nor does it allow you to dodge incoming fire. You can't level up your character, and there are no respawn points.
So what does it have? Silly accents. Silly accents, and a great deal of heart. Silly accents, and exploding sheep. Silly accents, and that mounting dread when, one by one, your squad is picked off by unerring robotic assailants. Silly accents and the triumphant swell of pride when, finally, the last of those ♥♥♥♥♥♥♥s is in your sights, and you are a squeeze of the trigger away from avenging your fallen comrades. Mostly though, it's the silly accents.
Buy this game - there are silly accents.
