Due to the recent inclusion of the FFA Gunplay game modes, I think it would be interesting to have a game mode inspired from the community. So here is an idea I've been tweaking. Sudden Death. This game mode would have 5 'waves' in which every minute the rules and the game change. For instance, the five waves would consist of the following:

• Wave 1: The game begins off normal
• Wave 2: Proficiences and Perks are removed
• Wave 3: Health is increased and bullet damage is  decreased
• Wave 4: HuD is removed, including the crosshairs, Friendly Fire is turned ON - health regeneration is turned OFF
• Wave 5: One life, no respawn
• If either player(s) on the opposing teams are not eliminated by Wave 5, the game enters Sudden Death - a flag will spawn in the middle of the map and the first to capture the flag and bring it back to the base claims the game, if not, the game enters a Draw

Leave your ideas or tweaks...
