Based on the v1.82 source code released recently, Zafehouse Infection amps up a number of features of the game, while adding a few new things for you (and I suppose, the undead) to sink your teeth into.

Version 1.0 is already up and available for play, and includes the following changes:

- Infection is now contagious, but there is a small chance to heal it.

- Weapons can be loaded automatically, and when giving a range weapon to someone, is it automatically loaded with one box.

- Barricades higher than heavy block survivors movement

- It is possible to weaken barricades to recover some supplies

- Survivors fighting alongside family members [survivors with the same surname] get an attack and defense bonus

- A survivor can only be cured once per hour.

If you’d like to help flap out, or just give his version a whirl, head over to the progress log on the forums, or check out the list of planned changes and ideas.

By far the coolest thing you’ll see all day and, most likely, all week.
