I am playing this FPS game called Chaotic Conflicts. It is multiplayer, and you can also play with super smart bots. Like I was getting destroyed by them! It’s really fun! The game does have a cost, but you can also play the demo (which still has Multiplayer), but only has 1 downside, which is the amount guns. It only has pistol, AK-47 and a shotgun! But the full game has more and also has minigame, like The Floor Is Lava!
