Hammer's:: New gametype server-side mod => OBJ

Following in MoH:AA's footsteps, this beta version of my OBJective game type works where SD left off. All bombs must be planted to win. Axis do not win by defusing, only be killing allies or map end. Place file under server's main folder and restart. Users similar cvars as SD, but they start with scr_obj_ instead of scr_sd. Also added: ham_bombplant, ham_bombdefuse, ham_bombtimer ... all in seconds to determine plant, defuse, and countdown times.
