Well, it doesn't come with any maps, but it showed the default valve ones for me... what i would do is go to your half-life dir, and in valve/maps copy crossfire, and paste it in pcjoes_mod/maps/
And yes, you will have to make the maps folder. After then you should see the map crossfire in your create game menu.
If you installed the mod correctly, then your default maps should appear in the map list, ie. boot_camp, crossfire etc... If they aren't showing up, try going into the console, and type map "crossfire" or any other map, and if it says error map not found, or something like that, you may have installed the mod wrong. This is a seperate mod, so it should go in your c: \..\Half-Life directory, not c: \..\Half-Life\esforces directory, hopefully you didn't do that...
This particle system will not be in ESF. The good part is that im going to be coding ESF's new turbo + power up auras. I want to really make a l33t transformation FX, with Hugh yellow lighting bolts, rocks flying around, ect. It should be fun
