Free? you gotta be kiddin' It's the official expansion pack for HL2 and it's coming out in April, I think it's priced at about £20-25 GBP (about $30-40, but don't hold me to that)
i remember valve releasing info on aftermath only beng like another 4 or 5 hours of gameplay and only costing about 8$ and only avaiable through steam, and possibly coming in a bundle with HL2. but im not sure if its the same pricing they released for aftermath cause of the HL episodes.
okay... so now that we told wiggy that we are intolerante of his national language...
that Half-Life saga site was extremely helpfull, you should all read it! also I boght that raising the bar book, should be coming tomarrow(I love free overnight shipping from barnes and noble in manahtan )
I'll tell you if it's worth buying, but because I love anything that has to do whith Half-Life and/or zombies, I will probally tell you to get it.
