FrugFrug, try doing this, transfer your map file (.sco) to native map files and rename it to scn_multi_scene_1. Then go into the scenes.txt and find...
scn_multi_scene_1 multi_scene_1 256 none none 0.000000 0.000000 100.000000 100.000000 -100.000000 0x00000001300389800003a4ea000058340000637a0000399b

Then you can host your game with bots I believe. Just go to Host Game then choose battle and choose the map Ruins.
