Pretty good Alpha run, its coming along nicely for sure.
I didn't run into any errors/black and pink textures/etc, except I did get stuck at one point in the screen shot below.
Had my toolbox out whenever I got
stuck.
For improvement, first stage:
Nothing major for improvement. The sun was somewhat irritating, especially when playing a non-sniper class. If that is supposed to be to block sniper's vision then its not really that useful because how easy it is to find little areas of shade. Also, maybe make the room underneath the house near the last point go all the way through and open up the path blocked with snow after the first point?
Second stage:
Pretty good as well. top part of the stage is barren, but I know you said you are going to work on that. I really didn't spend too much time in the tunnels, but they seemed alright as well. That one dark area right before coming out of the tunnel to the RED spawn seemed kinda weird.
Third Stage:
Needs the most work, missing lockers in spawns and the last point has only one entrance which really makes it congested. Definitely a second or third route to the last point on the third stage. I think that the ramp that the sleigh goes up at the end is way to tall/steep then again, I guess if it was much lower it would be really too easy for snipers.
Looking forward to the next test/release. Good luck.
