I kinda lost interest in TF2 for a while, but with Gunmettle and looking at all the 72 hour maps people have made I'm suddenly getting back into it, so here's a little update after looking over the one playtest I've gotten.
Updated to A3:
Totally reworked the spawn rooms.
Removed some of the catwalks.
Added some props inside.
Changed small ammo packs to medium.
