Back to School is a full featured Left 4 Dead and Left 4 Dead 2 campaign. The storyline is not interfere with none of this games and offer completly new setting of Borden city, struggling to survive in an epidemic apocalypse alongside with original 4 heroes. They are getting a chance to save themselves, since USA marines are coming in town and not falling back this time. But during the battle apogee something goes terribly wrong and local school - the most safe place in city - turns out to be a death trap.
Joseph P. Bracken (you might have heard him in "Pirates, Vikings & Knights II" mod) has kindly agreed to help and has already recorded cues for three NPC, which will communicate with the survivors on the spaces of our campaign. Yes, there will be NPC. There is nothing supernatural (like 3d models etc.), but would be cool, we promise you this. Effects also made by SoJa.
