You played Half-life Decay? Offical page It's a mod that allow you complete Half-life Decay on PC! I don't know what say more, but you need hl1 and atleast 35 MB of freespace :> P.s. Wiki
Re: You played Half-life Decay? Yeah played it other day with my friend. It's a nice mod, just there are some annoying bugs (eg name change on every mapchange, NPC's getting bugged if you press 'use' on them) I'd still recommend it though, tis a good game There are also secrets in there you have to find, and if you get them all the secret vort map is unlocked and you can play as vorts!
