Symmetrical koth-ctf hybrid
Both teams have standard A/D map final next to their bases but capturing enemy point changes owner of both points and starts koth clock. Kind of like symmetrical A/D but every time a team captures a controlpoint, attackers become defenders and vice versa. Play once and you get the idea quickly.
Not anymore, now the objective is to capture the reactor core (flag) to your base and hold it there for 5 minutes. The "attacking" team gets a forward spawn and reduced respawn time to aid in constant flag stealing.
