Indie strategy game APOX just released a few short weeks ago, boasting impressive 16-player comp-stomp on the co-op side of things along with single-player and competitive multi-player options as well. Now players will have another co-op option for the game as a survival mode was added just last week. Available in both single-player and co-op, players will have to defend their base for a whole 25 minutes as relentless waves of enemies swarm in. Players can enjoy this mode on not one, not two, but SIX new maps. Pretty nice for a free game update.
