You can grab the Lakeside map in the TA Zone map section.
Not a bad map. Seems a little bit like the Cold Place, but theres a broad shallow part in the middle where stuff can cross. As always, seeing some good players on a third party map makes all the difference.
The first 15 minutes of this game are solid, but pretty unspectacular. But it's pretty brilliant from there on out. Diablo does some hilariously risky shit with his Comm.
