[Sorry bout the long delay. If that happens again, just take control of 4-LOM. I've been pretty busy with a load of stuff at work. ]
[In addition to that, I had a possible thought. I don't think, a true smoke grenade wouldn't work in a vacuum, even with provided oxidizer, as any fire would burn up the oxygen really fast, and smoke wouldn't linger. Correct me if I'm wrong. However using a vapor of some kind should work. I'm assuming that's what's going on here, so no need to veto, just throwing that out there. ]
[Also, since Greedo lost some CHI, nows the time to bring up another rule. Greedo, needs to add some kind of setback to his next narration. Getting hurt, or tripping, or dropping/losing his weapon in some way. Something like that. However, keep in mind if he loses his weapon, he won't be able to roll against sniper till he gets it back. ]
[Anyway rolling against Droid Brain ]
4-LOM nearly losing concentration with all the noise and smoke, adjusts his audio receptors to only respond to statements by his comrades that include his name, and turns down the volume on all other sounds. Finally after a few more release of catches the gate's nearly open enough to fit the last person through, but then something unexpected happens. The last catch malfunctions freezing the gate. Zuckuss, Greedo, IG-88 and him may be able to squeeze under, but Bossk and Boba Fett will have trouble. 4-LOM reaches down and attempts to pull the gate up by force, but it doesn't budge. He calls to Bossk "Bossk! The Gate is stuck, we won't be able to fit underneath! I need your help prying this open and FAST!"
[ I had an idea for a possible house rule. Since this is a team effort of Bossk and 4-LOM (assuming Bossk narrates 4-LOM helping him to lift the gate on his next turn), after Bossk's description you should roll twice, one against 4-LOM's stats and one against Bossk's and then take the better successes of the 2 for both Yin and Yang. However since lifting a gate is not in 4-LOM's forte, he should roll against a 2 while Bossk will be rolling against a 5 for Strongman. So take the higher successes from whoever gets the better Yang, and then also take the higher successes from who gets the better Yin. If you think that's a cool idea. If Anyone dis-agrees, please speak up. ]
