Hi.
After last session i have a little problem. I think my players don't take things seriously. I don't mind a little humoristic situation but entire session was dominated by it. A quick rundown.
Tech priest acted like crazy and while i understand they are little excentric but after he sees a best craftmaship lasgun he say something like "gun, i love guns, guns guns guns" and started to running (image monty python style) towards gun ignoring that rest of regiment was fighting orks. Weapon specialist acting like he is some braindead warrior "kill the orks, orks bad" and other team members just joking all around. So after they started a bar brawl (cause it's fun) i stoped all this by a nearby commisar. Session ended in cliffhanger. Now i don't know what to do. I was thinking in executing one of the players which started the brawl but that seems a little extreme. Maybe execute on of the players comrade (who also had a part in all this) or just give them a reprimand. But i don't think this solves the problem. So beside doing something drastic how to create more serious mood.
