Combine storm your fortress, you have unlimited rockets, frags and smg ammo, and a big supply of batteries. Look out for the shotgunners and the manhacks coming through the windows :)

The combine won't start rushing you until one of the enemies has seen you, I haven't made the scanners come find you yet, so you can explore the map until you are ready to start the battle. I reccomend using "npccreate npccitizen weapon_rpg" to make yourself some backup if you're playing alone. It's also fun with friends in Synergy.

Don't expect the most intricate map in the world, but I hope you have some fun with this and that it was worth the tiny download for you :)
