Prototype Mk. 3

Description
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!

SIMPLE BUT CHALLENGING. It was manageable getting from point A to B. However, the hard part here was the scripted horde spawning on every checkpoints. Definitely recommended to get a player or two if you don't want to be stuck with bots and die often. Took a few restarts in the last few chapters due to it. Don't play if you're epileptic as well, the lighting wasn't designed to be pleasing due to the chosen aesthetic. Though I liked the idea that the survivors are some form of test subjects here. Overall, interesting map!

일단 맵 하나하나 길이가 만만찮음. 특히 막챕 피날레는 진짜 너무 길어서 루즈할 정도임. 그래도 맵 분위기는 좋음.

If you want to know how much of a downgrade L4D2's HMG is from L4D1's Minigun, play the finale with Cuba's mounted gun randomization script. The different between two miniguns and two HMGs is night and day.

The bots are absolutely hopeless in some places. At least one other player recommended.

One of the stupid map I'd ever played. The finale is way too long, what's the fun of just standing there and spam?
