As the typical dick, I like to find ways outside of the map or find glitches... This map makes it too easy. I played the map for 30 minutes, and I already got myself stuck inside a barrier. Let's go through the things I found.
1. Clipping...
The clipping (Player) is not that great. Able to get onto the truck in SoE, able to get onto the upper cell block in MoTD, Was able to get behind the box in Buried, and there's probably a lot more...
2. Pathnodes areas
Half the time, the pathnodes seem to just give up on the map. Seems stupid, really.
3. Guns...
There's only like, 3 gun that you can actually buy. Other than that, all wall weapons are just a grab. You don't need to buy them.
I'd like to say more, but I don't want to write an SAT essay on UGX.
