hi,

was just wondering if you guys release worms reloaded on pc, mac, psp and iphone it would be just awesome if people could actually play online together independently of wich platform is being used.

Since Worms Reloaded uses Steamworks for multiplayer it's unlikely that PSP, iPhone or other consoles are able to play with PC users, if they ever release it on other systems than PC.

MAC on the other hand is a possibility thanks to SteamPlay. They just have to create a MAC version.

Since Worms Reloaded uses Steamworks for multiplayer

Dont misunderstand....Worms Reloaded will be in Steam for download, and we need Steam to play it.....but that does not means it will use Steam servers for multiplayer and online issues.....there are lots of Steam games wich have their own servers or uses another service apart from Steam for the online play (for expample: Flock! uses gamespy//Altitude uses own server//Audiosurf uses own Leaderboards, and not the Steam ones)
Altitude is a Steam game and it have cross platform multiplayer(Mac/PC) BTW....

I think it was confirmed at some point that Worms Reloaded will take advantage of Steamworks. Dunno if they'll go for a Mac version though.

Cross-platform play between platforms like PSP/iPhone/etc is virtually impossible though, the games run on completely separate online frameworks.
