Hello, and welcome at Back to School ModDB page! Recent months we had some serious research, and we managed to solve a lot of hammer-made puzzles. We have decided to release campaign for L4D1 first and, after that, port it over for L4D2. And yes. we are planning to release top-quality campaign, but, you know - there is only two of us in a team - and this project takes a lot of time. So be more patient guys! :)
And we have three more good news for you:
1. New developers video - new custom particle systems and.. some more!
2. New screenshots: 1st chapter "Forest" (complete)
