Remember a year ago when we did the gamemode jam? Remember how we only got "end the game as fast as possible"-agents out of it? These were the two other not shit gamemodes in the pack. Pete disappeared so the jammin project went down the drain.

These are largely untested so be warned. this is mainly to get feedback on the concept and play of the gamemodes anyways.

HOTLINE: by @Petethegoat 
The singularity is upon us: an AI at Centcomm has achieved superintelligence. Follow it's sadistic instructions and maybe there is some hope of survival.

CRYSTAL: By @Giacom 
There are 3 crystal zealots each with their own unique crystals, which have powers that you can activate by clicking while in your hand. Each zealot must collect 2 crystals to complete their objective; they can find more crystals by examining their own crystal and it will glow depending on how close other crystals are.
won't this select the first crystal in the list instead of the nearest crystal? it should probably check the nearest one.
