At Anime Expo 2016, Aksys Games announced that they will be porting Aegis of Earth: Protonous Assault to Steam. Originally, Aksys released the game on PS4, PS3, and PS Vita back in March. A release date for the Steam version has yet to be revealed. The company described the game:
A frenetic and explosive new spin on action strategy gaming. Dig in, plan out and build up your defenses as hordes of hulking monstrosities bombard your heavily fortified city in an attempt to wipe you off the Earth for good! Command the last bastion of humanity as you fight for the survival of the species utilizing fantastic tech, cunning tactics and massive weapons in an all-out action strategy extravaganza!
This announcement comes straight on the heels of XBlaze: Lost Memories also being announced for Steam.
