Anyone can actually participate in beta-testing, but this is closed beta, so I want it to be done as professional as you can. If you want to take part in it - email me with:
1) Your system configuration
2) Your beta-testing experience
3) Your mapping/coding experience
All testers should remember those simple rules:
1) You shouldn't give this beta to anyone else.
2) Your error reports must be easy to understand and you must write where, when and how this error occurs. Not just "You have bug with zombies".
Remember - I know about lot of bugs already, and some of them I can't fix for now. So, don't think that your buglist will be completely fixed.
ATTENTION (+1 Edit)
First bug is already caught, file w_rocket.mdl is missing from /models/ folder. You WON'T need it in game, I just forgot to delete this from code, so pick random model and rename it.
In case your game asking for editor.wad - here it is - link
