Over the last few days I've been working with izzy to bring this game mode to life. After trying many different prototypes, I think we've found the "true" gameplay of this mode with the "Cat's Eye" map running on aloha now. At this point I think it's ready for more public comment.

This is how the game mode works(taken from the wiki page I wrote up):

In this mode the map is "controlled" by placing or removing blocks - so building on new ground is one way to gain territory, but tunneling into enemy territory and destroying their structures can be even better, since it removes control from them at the same time.

Each x/y coordinate controlled goes towards a "sector" score - each grid area is a sector. Controlling more blocks than the opponent wins the sector. Each sector controlled is worth 1 point per tick(of 30 seconds).

Scoring only adds the balance of points: If Green and Blue control equal amounts of area, no points are added. If Green controls 1 more territory it gains 1 point per tick.

CTF gameplay remains active but you can add a high cap limit to discourage it.

The Cat's Eye map is designed as a sort of offspring of Pinpoint and Hallway; the big central tower plays a major role in providing sniping positions, while the surrounding area is just high enough to allow trench warfare. I've been surprised to see what people are doing with it :)
