“it's a good game. although the only multiplayer servers almost only have one to 10 people so singleplayer is the better play option. plus the playtests are better then the public version from what i have heard.”
“runs pretty good, multiplayer is mostly iffy but it is early access. good updates and good physics. overall good game if you want a shooter that can run on moderately old or not super great hardware”

“You'd think the way my account is, with over 1700 hours in Squad, 1700 in CS, and thousands of hours in the Insurgency mod for CSS, Insurgency the game, and Insurgency SandStorm and other tactical shooters, you would think this game would be recommended to me, but it was not. I…”

— a player, Steam review · 16 hrs played“More than 3 years later, this game still blows. Lack of effects, everything feels off, sounds are horrific, it still looks like an unfinished school project, the vehicles are a joke, i just ran through barbed wire in a bike, amazing. Maps are as basic as it gets aswell”
