,,Well, well...isn't this just like...OLD TIMES,, ? This is Old Times mod, and the goal is to restore the original Half-Life 2 Story with all of his content. Unlike other mods, OT will use the original beta content from the leak, but will be competed and full fixed.
That's right! This is the Air Exchange. Air Exchange was a chapter featured in Half-Life 2 beta cca.2002. It was completely cut from final game, and even from BETA. Still, this pack has a bug, the map d2_airex_start is dead.I can't fix it because I'm not a mapper, but if you'll find a fix or can fix it, tell me.
