 Moreover, the fists can be improved by investing skill points in their respective category, which now replaces the swimming skill (which was considered by many to be fairly useless).Other than that, the weapon arsenal was also upgraded, featuring several katanas, three new grenades, a napalm launcher and a rifle which fires PHAT rays (PHysically Anamorphic Transmogryphing rays which cause living targets to swell up until they explode) and rice bags as secondary ammunition.In addition to several other completely new weapons, the mod includes unique versions of some of the original weapons, pre-customised to suit the needs of particular characters.
