Moon Research Lab 2023

I introduce you - The new and improved moonbase "Revexomalum" , based on the famous moon research lab "Exomalum" which was abandoned.

The base has new features and areas , but beware... Surviving will not be easy as it was before...

To start the survival , there is a console desk inside the main base (spawn area/house) that will have a glow when you go near it. Press E or "use" button on it to start the survival.

Man this would go great with the space mod but i don't want to play survival because i don't trust random players... And my steam friend plays L4D2 but never really plays..

What do the chinese/japanese/asian words mean? I can't seem to find the translation.

I agree with Robro 208, make a campaign out of this.

Hey, i'm back. This map ALSO conflicts with custom witch music. If it was any other special infected, i would understand. But witches don't appear in survival... So why does this happen?

Can you some how make a Campaign out of this, like, maybe you can make 3 levels and you have to escape the moon and every Level is like a sector of the Moon Base. Anyway, the map is awesome.
