This is pretty sad. I played to every GRB version, nazi-zombie and survivor. I still have your launcher on my computer and I check if the server is available, not anymore :'(.
Release all your files is a pretty hard decision because a lot of emulator will pop-up and the player base of infestation will be more bored.
Release will help a lot of people who know how programme (a bit) but not with the same level, I'm thinking about the ts3 cracked.
Release flash could be awesome, I mean PSD files because I tried a lot to photoshop every background to remove icon and more but it is up to you, I tihnk all poeple who got it, like the WarInc flash sell it for +1000€
Models, well I never try to make and add new models so, I think that is a good idea to release for ppl who want to learn modeling otherwise ppl will juste add it in their game and byebye credit, all that work done.
Release your games, DeadZ and GRB is the harder decision because that will spam the RageZone server section. A lot of ppl will just instal these sources on their server and that all, make money and close after two weeks. I higly prefer to get tutorial than the full source but it will be more work for you than post a link ^^.
Sad news, you were one of the guys who worked well on WarZ, funny guys, sweet guys who never ask for money when I needed help.
