New trailer out for this long-awaited game, due to be released this summer

Even though it goes against my antipathy to FPS games with non-human lifeforms (the reason why I won't play Half-Life for example), the prequel to this game (Return to Castle Wolfenstein) is what got me into FPS gaming and I very much enjoyed the multiplayer. If any of us enjoy the MP, hopefully we'll be able to set up a server for it

A bunch of multiplayer screenshots were leaked, but Activision claims "The screens in question were not distributed by Activision or approved by Activision, and thus Activision cannot confirm their authenticity."
