@ Talented Doge: The link between cs2d and the mentioned games is "cool", not "top-down shooter". It would make more sense to write "top-down shooter" but I guess he's just asking about other games that are cool and similar to cs2d (not necessarily top-down shooters).
Talking about Paintball lol, you can check out Roblox, It's a game who got the same graphics as Minecraft but there are lot of servers and mods which can be really fun when you're boing or playing with friends
Ok, imo the game that is kinda similar to cs2d and is probably better than cs2d is bf 1942. (no offense dc lol), you can get it for free on abandonware legally. ( no please don't ban me )
