This game is reliant.
A faithful re-imagining of a well established franchise, not only are you able to control up to 50+ space defenders in infinite mode (literally raining munitions upon the ground), but to me at least, the best part was the very moment that I realized the most efficient way to play the game: Strafe left, drop down, reverse direction, and repeat.
I just find it absolutely brilliant that as the player, you end up playing just like the programed enemies of this classic game; great work!
