Description
Project Lambda is an ambitious project aiming to re-create the classic shooter masterpiece, Half-Life, often debated to be the best game of all time that revolutionized its genre, in Minecraft. It is a complete rewrite and overhaul of LambdaCraft, permission for which was kindly granted by its owner KSkun.
Warning: Project Lambda is still in beta so expect a few issues, hopefully no game breaking bugs though. I am looking for testers so I urge everyone to report any found bugs on my github issue tracker.
Hopefully soon. ;(
