The Island

The Island is a mod for Half Life 2 that allows a single player to travel to a deserted island where you won't be as alone as you first thought.

This island is populated by Zombies and other equally fearsome creatures that have taken control of the island and are wiping out everything. They're really hard enemies to beat and you'll have to create a strategy for each situation. You're alone in the face of danger.

This mod is free but to install it you must have installed on your computer the original game Half Life 2. If you are a little skillful you can create your own missions editing the game.
