I’m going to start working on Chiron TL-34. You should go to the community creations section where there is a map remake thread. People are posting stuff there.
My plan is to build “Sniper Alley” (a name I made up myself). A map that is specifically designed for real sniping, not shotty-sniping. It will be heavily influenced by “Blood Gulch” from Halo Combat Evolved.
Like “Blood Gulch”, there will be a large, fairly flat center where roaming through it would mean easy pickings by your enemies. The edges of the maps will have long corridors which are connected to various towers which overlook the flatlands. Those corridors will also have minimal coverage. Thus, the only place where true coverage can be found is within the towers, encouraging players to take refuge in them.
My hope is that there will be a true sniper shootout the way sniper rifles are actually used, not the way they are abused in current Halo fashion.
