UPDATE 21/5/09: I've released V1.2 of the map. I've: Made the stairs easier to run up; made the holes in the wall bigger; made the bookshelves out of brushes so they're unmovable and unbreakable (allowing you to break them resulted in a spawn point being exposed); fixed a glitch that ocurred if you stood in the doors when they were closing and made the vents easier to crawl into. ----- My first deathmatch map. Please be as harsh as possible with your comments, as I want to find out how to improve more. Save to C:\Program Files\Steam\steamapps\username\half-life2 deathmatch\hl2mp\maps. Replace username with your Steam account username.
If it's a library you should at least add a few books.
Originally there were, stacked high too. Damn it lagged. However, I could probably add some (say, three per bookshelf) without any adverse effects.
Books would be a good idea indeed
