James Falcon crouched in a corner, hidden behind his meal tray. After taking down the robot, the group had wasted too much time picking themselves up, prematurely congratulating themselves on their victory and then crossing towards the exit. It had been dangerously stupid, in retrospect. He had almost gone to remove the warden's power pack as had been suggested in the PDA, but after the big reptilian thing stepped on its head, he hadn't bothered. He vowed to himself to learn from the mistake. Cockiness led to taking chances, and taking chances led to failure.
The tray-shield shook again as a foam canister struck hard, but the wall held. He had had to grow the plastic to a almost metre thick to protect himself, but now that it had held the foam would end up adding to the barrier, giving him a little extra protection. Falcon dared to peek around the edge for a moment, and all seemed quiet. His fellow prisoners were all cowering back under the continuous assault.
All had gone quiet below as well. The sounds of struggle had faded, so it seemed that the other prisoners and robots had all been caught up in the rising tide. What he saw when he looked behind to the shaft, however, was that the water hadn't stopped being pumped in. Another stray foam capsule had mostly resealed the shaft after the first covering had been burnt away, but a few cracks in the foam spurted tiny jets of water up from underneath. Perhaps he could use this. The robot's whips crackled with electricity, but if it could be doused in that water, it would fry its own circuits.
Silently, he expanded the sections of foam around the pinprick holes, cutting off the water. He would need the pressure to continue to build below while waiting for just the right moment to release it. He didn't have a way to redirect the geyser that would burst forth once the foam cracked, so that meant he would need the metal giant to stand in its way. It had to be baited.
"Hey!" He yelled at the warden as he stepped out from behind his cover. "Are you going to stand there all day wasting bullets, or will you come over here and fight me?" He put extra emphasis on the word here, trying to alert the other rogues to the importance of moving the robot, but hopefully not while alerting the thing itself. If it sensed a trap, it wouldn't move.
