I did. They created more combat monsters.
I haven't got a clue why they're sofocused on their combat abilities. The only two fatalitites we've had was when they met their first toxic spirit, and when one of them critically glitched a demolitions test. My fun has mostly been about them experiencing the awesomeness of the Sixth World. None of them are very familiar with canon, so I started them off in 2050, and we're just about up to the Universal Brotherhood storyline. I suppose I could use their combat-mindedness for an all out bug hunt scenario.
I guess I'll ask them what kind of campaign they want to play. I don't mind playing a merc type campaign, it's just annoying to play a "normal" campaign with their current characters.
Thanks for your thoughts, everyone.
