I just thought I would tell everyone how to get weapons earlier in the demo for fun. Its quite simple, but it took me a while to find it. You MUST have atleast 1 player as an AI to make this work.
- Open up the console,
- Type in "sbgiverandom_weapons"
- A random weapon will be given to the AI and they will drop their old weapons.
- Repeat the process to get the weapon desired.
Its quite fun do noclip ontop of buildings and such and snipe zombies :)
