Existing Full 3D game, needs new functions added

Hello, I have a full 3D game that needs a few new functions. I'm looking for some one with GAME DEVELOPING background and plays videos games and has a understanding of game flow. Army Antz is a 5 vs 5 battle area game play with RTS (real-time strategy) style, the user moves the characters by tapping the screen to set a location and tapping on enemy's to target. Army Antz also has Multi-Player function using Photon Networking * Team Deathmatch Survival (EDIT) - This game mode exist in the game right now but is only 1 round. I need it edited so the game mode has 3 rounds best and the teams switch sides if possible. * Survival Game Mode (NEW GAME MODE) - I Need a new mode for survival for 10 players. Match ends when the user with most kill score each's goal. 1vs1vs1vs1vs1vs1vs1vs1vs1vs1 - need a single player mode for practice with A.I and a multiplayer online mode * Killing KOed Dizzy ants (NEW FUNCTION) - allow user to shoot KOed ants. There death timer will decrease faster and stop player or a.i from using revive, killing the ant faster. * Revive Character (NEW FUNCTION) - I wanna add a function so user can use a normal ant to revive a dying ant BUT leaves ant wide open for attack. - while normal ant is reviving dying ant, death timer goes backwards, then ant is revived with % life. - allow user to heal ant's timer giving move time for user to call medic as if user decides its to risky. * Manual Analog & 3rd person (NEW FUNCTION) - Need a 3rd person camera added (new button added for user to change between views) - Manual Controls, so user can move character with analog and fire weapon with a button (new button added for user to change between manual analog/semi-auto controls)
