Is Natural Selection (for HL1) worth the download?
Actually, what mods appearing in Steam are worth the download?
NS is not for everyone. Its a tactics meets twitch based combat game that I garantee youve never played before (even in savage). It takes time to get into it, to know what stuff does and how crap works. The learning curve pays off into a 10fold funner game than anything else on the market if you master it, though.
edit: as far as im concerned, there are no other HL1 mods.
