Wow, this map is full of bugs. I fixed all leaks, errors and warnings. Now, there shouldn't be any problems to test the map ingame.
You should definitely do smaller and more easy maps first. You need to learn the basics about mapping and you need to learn how BSP works. This map is to complicated for a beginner (don't use teleporters or target_spawners, if you can't set the keys for the base, the info_player_deathmatches and the worldspawn correct).
It's easier to avoid leaks if you use only the 8 or 16 unit grid.
Btw, I detailed all barrels for lower numportals.
