If you want play some maps, after, you need some models,sprites and wads,
you need: NULL.mdl, lasergun_balls.spr and spawner.wad (for spw_spawnzone.bsp),
I work in a patch for fix it. however, you can copy some models and remplace the name for NULL(i recommend that find and copy the "shock_effect.mdl"), in the lasergun_balls.spr you can copy and remplace the name of Glow03.spr, in the spawner.wad, i need upload the wad...
Later of ths changes, you can run Spawner Rescued Version, remember that errors as this can appear in the game.
If appear news errors, please comment or send me a private message.
Appart, now i work in the new code for can upload the original Spawner v1.1
