I hope someone will give me a positive answer...

there is Multiplayer. i would assume its dead unless you got friends to play with.

Well, I played a couple of MP games. Funny, but deathmatches can't compare with what a in_this_kind_of_game co-op would be.
I bought Painkiller Hell & Damnation Collector's just a week before buying Painkiller Black Edition here on GOG (because of curiosity and thanks to the sales) and it's funny (/sad?) how both the games seems to be incomplete.

Painkiller HD has the amazing coop, but it's a downgraded version of the original (better graphics can't replace missing enemies and levels). Let's see what will happen now that tools to create mods are freely available...until now, Nordic Games just released a bunch of DLC, even for a simple alternative MP mode. Their intentions are pretty clear, just trying to milk Painkiller HD users - they won't receive from me a single euro.

Painkiller BE features what it successor lacks (levels & enemies), but lacks what it successor features (co op - graphical improvement isn't significant, IMHO)

Being Painkiller BE cheaper and having low HW requirements, giving possibility to increase the number of enemies without killing performances, I still hope someone will give it a co op mod.

Just for clarification, Black Edition is the original Painkiller: Heaven's Got a Hitman, and Painkiller: Battle Out of Hell expansion on a single DVD. Those are the only Painkillers made by People Can Fly. Rest of the expansions are much newer and made by someone else.
