“Finally, a game that's ACTUALLY like the original Ghost Recon instead of a room-clearing simulator like the countless other SWAT/Rainbow 6 type games! Wish people would stop comparing this to them since this game…”
“Very fun game only hitch is the Enemy ai is lacking, Even on the hardest difuculty its like they have been Lobitomized several times. However this game is like Ghost recon, Arma and RoN had a baby. Want a tacticool…”

“Black One: Blood Brothers is a tactical shooter that deliberately rejects modern design trends in favor of a slower, more methodical approach rooted in classic squad-based simulations. Developed and published by Helios…”

“I myself am a gunsmith/developing mechanical systems designer so I'll approach it from that perspective as neutrally as I can. To keep it short, I really enjoy it! And I'm actually glad I bought in this stage because I…”
