Is that a new Space Hulk Version or one of the old ones (Space Crusade? Is that the same game?) I remember we had it over here but it was called Star Quest and all weapons were retconned to be non-leathal. Truth be told, I only found out about that last year when I realized the fucking Meltagun was changed to...I don´t know some Time-distortion gun or something that removed the enemies (which were all described to be robots btw) from this plane of existence or some such shit. Retrospectively I think the supposed weapon effect are pretty cool though, even if they are apparently non-leathal, freezing someone in time or banishing something from it home-plane is some sinister stuff...
