Okay, here's what's been happening. My group have been going along their missons and came out unscarthed in every one, except for a scum who lost his leg in one encounter and then asked his cell-mate to shoot him dead permanently. In short, I believe I'm being a little too easy on my players, and they're about level 3 - 5 at the moment.
So, now they''ve come to the pivotal point of the campaign, the BBBG (Big Bad Boss Guy) that caused most of the problems. They've met the BBBG early on once and now they have to defeat him.somehow, or at least find a way to escape (but the latter is not an option since the BBBG doesn't want them to just run away). Oh, the characters are inside the warp and on a space hulk where the BBBG is, courtesy of a rogue trader, and he has the ability to phase....so, no easy kills. They did get rid of a roomful of extremely tough & difficult to hurt zombies by throwing bombs at them.
I don't want to railroad my players but I also don't want to make it easy for them to defeat the boss, either. I'm not going for TPK and I don't want them to think I'm out to do this. Any suggestions on how to handle the encounter?
Thanks in advance.
