Sky Mesa puts you back in the shoes of Gordon Freeman. Sky Mesa is a little map pack for half life that has 4 new playable maps. There are no new weapons nor enemies in this mod. (There are some new textures though.) Just the same ol'half life weapons. There is however, a cameo from an unused HL1 monster.
Here is the WON version of sky mesa. Yeah I've been taking lots of time to make this version run smoothly. I hope you enjoy. Read the description for more info.
The WON version isn't any different than the steam version. Except this time it is on the old half life engine. My personal fav. I have taken lots of time to change things around in the folder and make this mod compatible with WON. I had lots of crashes on WON with this mod but I took care of them. I even changed the readme to tell directions on how to make the mod run through WON. It's pretty simple and kinda a bit easier than getting the steam version to run. Anyway, enjoy this version of Sky Mesa. BTW, i am working on an addon to sky mesa that will be added onto this page. Stay tune. :)
