Chopper: Attack helicopters - Rencounter

DLC Rencounter opens PVP mode in the game Chopper: Attack helicopters, where you can enter into battle with a real opponent.
Both players have equivalent bases.
Each player must defend his base from attacking enemy ground units, and try to destroy the enemy base.
The base consists of a helipad which restores armor and ammunition, tower to be protected, and spawn points of ground units - off-road cars with heavy machine guns
