Hi,

To play Invasion Offline, unzip invasion_2.1-L5.5_offline.zip in your tremulous folder and run invasion.bat (windows) or invasion.bin (linux)
it run a local server on atcs, you can callvote others maps (or use !map) and callvote invasion (or use !invasion)

There are actually 9 maps with invasion layouts: atcs, atcszalpha-b2, utcsb2, utcs, tremor, niveus, atcs-2yb, atcs-onice-b1 and stargatecommand-b1. The new layout system allows you to callvote several layouts on the map you’re playing which can be know with !listinvasion command (all layout names must begin with "invasion"). You have to use it like that: 

Either /callvote invasion (8 bots and default layout)
Or /callvote invasion [number] ([number] bots and default layout)
Or /callvote invasion [layout] (8 bots and layout [layout])
Or /callvote invasion [number] [layout] ([number] bots and layout [layout])
