The 'Swarm' zombies all come from one direction and are easily killed before they even get to the fort, so there is little reason to build one in the first place. almost every mission is run around map until you find the fort base platform, power it with blueglow that is randomly found on the map, build your fort, then activate and defend for said amount of minutes. As for the game itself, I have played 5+ hours and while the game is fun, it is very buggy and get repetitive fast. On the back of the game case it states 'Online Play Required'. Wow, so much hate for warning others that the game is online only and for paying $60 for a Early Access Beta.Īnyways, most of the confusion comes from Amazon's inaccurate description of the Game.
