Prototype Mk. 3

Participate in the Synergenic Technologies Inc. Hazardous Environment Teambuilding Study. Fight through teaming hordes of the infected to escape the testing area. Inspired by eighties and nineties era sci-fi aesthetics, the campaign is designed to start simple and become increasingly difficult as you progress.

The campaign was also built for L4D1, but is only available on L4Dmaps.com.

I can't believe this campaign has been up for a decade now, and I can't believe new people are still discovering it. If you enjoyed this map, please share it with your friends, and if you'd like to go a step further you are welcome to help support my caffeine addiction by buying me a coffee here: https://www.buymeacoffee.com/jonwhitley.

Sincerely, everybody, thank you so much for playing!
