Showing off some of the mod. image - SMOD: OUTBREAK .98c (STEAMPIPE fix) for Half-Life 2

Outbreak might be best summed up as an add-on to the original SMOD that encourages the same frenzied action as it throws a generous number of hostiles at the player, especially zombies. Following its base, Outbreak's arsenal includes usual suspects like the G36 carbine, as well as less conventional ones such as a katana that gives the player a speed boost.
