there isnt a simple variable like "swep" with .race mods but you can set any weapon by setting "wep = (wep_name)" in #define game_start . you should also set the starting ammo with "
ammo[weapon_get_type(wep)] = typ_ammo[weapon_get_type(wep)]*3
" which sets the ammo for whatever weapon you have to 3x the amount that a ammo pickup gives (what the base game does)
