crazy played both of those. nany many years later when i looked into the build engine finally :'D
my game was HL and CS (later days) which got me into modding so years after i looked at build engine.
i made for worldcraft a human launcher one day (ripped entities from some HLDM map by valve) and that got chucked into awp_1337_sk337 (by other guy, superjer).
miss those times :') still occasionally crack open the worldcraft to make a room with zombies and nades!
