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.
A fine half life mod, very entertaining.
Good texturing, interesting level design, game difficulty well balanced.
Can be improved a bit more in some details.
No evident glitches nor crashes during the gameplay. I still play it whenever I have some spare time.
I like it.
