Map:
Landing Bay - Jacob's Rest by ModdedMarionette
Mod:
Left 2 Mine by TheCallunxz
Map Requirements:
You must have Left 2 Mine installed. (Left 2 Mine: https://www.curseforge.com/minecraft/mc-mods/left-2-mine)
This is a project on recreating Alien Swarm's entire Jacob's Rest campaign as a Left 2 Mine map.
Because Alien Swarm is also a COOP shooter, its map works well for Left 2 Mine since this mod falls into the same genre.
So far, only the first chapter, Landing Bay, has been completed and released here as the DEMO, providing you a taste of what to expect from this campaign when it is finished.
Eventually (god knows when) when the whole campaign is completed, it will be released here as well.
