"Who?" Shelton peered down the corridor. "We're here."
A sign on the corner up ahead pointed to the left reading: Lab 101.
"Hmm. Let's check it--" Shelton turned the corner, and froze.
The hallway suddenly got very, very large, and a hulking Dragonstorm experiment stood in front of the doorway. It was coated in plates of armor, and when it saw Shelton giant claws extended from it's hands.
Shelton dove across the hallway into the adjacent lab, seconds ahead of the charging experiment. Slamming the door locks, he felt the entire lab shake as the experiment started beating the wall down.
"Dammit, dammit, dammit..." he repeated, pulling out drawers frantically. Nothing. All he had was what was in his possession now.
Cracks started appearing in the wall. The foundation was coming apart. Shelton had no chance of defeating it, but maybe he could distract it...
He released the valve on the propane tank and threw it through a hole in the wall, further down the hallway. Then he relit the battery with the steel wool, and threw it after the propane tank. The two ignited to form a momentary fireball.
The experiment lunged at the fireball, slashing the remains of the propane tank. Shelton took the opportunity to barrel in the other direction, into Lab 101.
