Here's the .pk3 with the decompiled source included. I used it to update the entities via q3map2's
-onlyents option. The .map could contain bugs and may
not be suited to continue the development of this map. You're probably better of by just copying the pickup_money and info_player_deathmatch entities. If you take a look at this .pk3 you see the dm_/br_ *.bsp, *.aas, *.ai, *.tex files are identical. In contrast to my earlier expectations, this added ~4MB to the .pk3 size.
