Extraction:
I would really like to see a gametype where you all start with a set amount of money and can buy different weapons, perks and AAs. Each player has one life and once you die you lose the weapon you had, but keep the AAs or perks you bought. The more money you earn by hurting/killing enemies, the better things you can buy. By the later rounds you can have stuff like a shotgun, sword, sniper etc… This would also be an objective gametype so the round can end by the objective being completed (a flag being captured or bomb being armed or something).
Please post your gametype ideas ITT.
