I noticed on the github site that fr1tz is working on a territory generator structure of some sorts. What it is for and how would it integrate into the ETH mode?
Territory generators are primarily intended for CTF mode. They're simply structures that create a territory zone around them. First version of CTF mode will probably feature two kinds of generators: Large and indestructible (to be placed by the mapper) and small and destructible (to be dynamically placed by players).
