My latest map is finished! I tried to break my typical style of huge maps and challenged myself to make a small and short map. I started out making a 1024 map but ended up making something a little bigger. I'm glad I can finally get to use Otex textures.
Gameplay is fast and intense and a bit slaughterish with a lot of close-quarters combat and continuous action. This map is difficult but not crazy difficult and there is plenty of health available. It's absolutely possible to complete this on the first playthrough. 
Ammo consumption and balance is a strong gameplay mechanic and while there is definitely enough ammo, you'll certainly want to be careful how you spend shells and bullets etc. I've playtested this many times and most of the time, after the final monster i had just a few shells left. The map has a chainsaw at the start of the map so that can help with ammo balance but I think most regular Doomers wouldn't have a problem.    Story: In a desert crater on Deimos lies an ancient UAC storage facility.
