Quake3World

Help me! I'm trying to get the missing files from q3a demo like Bfg and grenade launcher images,
maps, characters, and stuff like that but I don't know where to get them. Help!!

There aren't any missing files in the demo. Try re-downloading it.

I believe the missing files you're referring to are the difference between the demo, and the full game.

You can buy the full game from Steam.
