Colossal Titan ( Gamemode )

 The Colossal Titan (Gamemode) is a gamemode that centers around the Colossal Titan.

In any servers with this gamemode at any type. The round starts by the Colossal Titan appeared out of the thin air, causing other players to have a temporary white screen in their screens. The Colossal Titan will try to kill any players as its first move and later. It will kick the gate which will send any players near it flying unless they are grappled on a surface. Initiating the fight against the Colossal Titan whilst the others defending the Civilians from the Aberrants

Colossal Titan
The colossal titan is near the wall, smashing and killing the players. It also kicks the wall once, at the beginning of the game. Aberrant Titans will flood from that hole in the wall, and attempt to run towards the other end of the map. The game ends when the Colossal TItan is killed, or when an abnormal reaches the Civilians. Players will not respawn.

Strategy
The fact that players do not respawn makes this an EXTREMELY difficult gamemode. Have most players handle the abnormals that flood in, and have one or two players try to kill the Colossal Titan. This is good, because when players crowd around the Colossal Titan, he will gas the yellow and red gas, mass killing most players.

Colossal Titan II
This is essentially Colossal Titan, but the players will respawn after 10 seconds. To compensate for this, the Colossal Titan has higher nape armor.

Strategy
Half the players should handle the titans below, and the other half should attempt to take down the main threat. The extremely high number of players allows mass swarms to reach the Colossal Titans nape. They will chip down the napes armor, eventually killing it.

Alternatively, you could have 2-5 skilled players handle the Titans below, because the Aberrants that come through generally don't come in packs. The rest of the players could attempt to kill the Colossal Titan.
