Survival 101 is a Half-life 2 mod that I've been working on for sometime now. The concept for the mod is that of survival/horror. It borrows elements from games such as Resident Evil and Bioshock. Major changes to the Half-Life 2 experience include: realistic weapon damage (no more emptying entire clips into enemies), scarcity of ammunition and health packs, and more of a focus on the horror aspect. The mod features its own story line which will hopefully span at least to the two hour mark.
