Obsidian Conflict Lead Mapper. Here is a list of my released maps (Beta and map series extentions not included): aim_akm4ruins2, ty_volleyball, aim_cabin, aim_gardens, ka_hockey_tysn, zm_backwoods, zm_basin, syn_fireteam, oc_manor, oc_stitches, oc_breakout, oc_courier, oc_fireteam, oc_harvest, oc_lobby, emp_coast, oc_starship_troopers, aoc_kingofthefort, oc_wildfire
oc_lobby is obisidian conflict's default way of selecting a map. Within it are a set of doors leading to other maps, which can be entered by breaking them down with your crowbar. There are doors leading to every half-life series games' chapters, as well as an area for selecting custom maps, shown in this picture.
AWESOME!
