The Island is singleplayer first person shoter mod for Half-Life 2 where aren't any logical obstacles. It's just PURE and very hard action. And who is your enemy? It is army made by all kinds of zombies (especially by fast zombies) and their headcrabs. Where is it happened? On any usual island (it's secondary, story is secondary too).
Mod is already done and betatested, but it isn't translated to english.
You can see six screenshots that should show level of leveldesign. Another ingame pictures comes soon.
