A tower defence inspired game mode

[Solarsyphon]

Part of the problem with CC being unpopular is none of the game modes tailor to it so I have a suggestion that I think might help.

My suggestion is a game mode inspired by tower defence where enemies are trying to get past you to reach an end zone. Like how enemies prioritise defence targets in this mode they would prioritise reaching an exit and if too many enemies get to the exit you loose.  Its a flexible idea off the top of my head I can think of it being any unit running past,  specific enemies running  among a crowd of normal enemies  or special heavy units like the thumpers trying to get past. Basically it would be like a defence but the focus would be more on stopping enemies moving rather than killing them.
