Looks like battleMETAL will fill some Mechwarrior 2 nostalgia
Just came across this cool video and project which aims to implement a Mecha game and SDK on the Quake1 engine ( Darkplaces specifically): You can find more details on their website and the Github repository . Art assets are apparently not available yet due to some non-free placeholders, but I hope this will be changed soon. Also no multiplayer, but that might be possible to fix . Also really cool would be a Occulus Quest VR port via the already available and quite awesome Darkplaces VR port called QuakeQuest . Leave a comment on our forums.
