>>95916901 (OP)Literally last session. The PCs took a repurposed warhead down into an ocean rift, and fought a giant sea monster. The kaiju wasn't the target, just a local, but it severely complicated their plan because it wrecked their robotic manipulators, the ones used for precision work. Precision work like arming the nuke. They salvaged the situation by triggering the bomb's fail-deadly system, but that meant they had to haul ass to get outside the blast radius before it went off. The PCs almost didn't make it out in time. The one in the fastest mech had to push the slower one to help him reach the safe zone right before the (combat round) timer ticked down!
Hmm. There was also another game in a different system, where the PCs were in bigger (bio)mecha and fighting a kaiju. They were doing really badly in the fight, and the monster kept regenerating, so they called in a nuclear strike danger-close. First PC had to shield the second PC from the blast, and nearly died, leaving the wounded second PC to finish the kaiju off with her remaining arm and the first PC's knife.
