Mercer started to turn as Rex came around the side, but the weight of his shield slowed him down as he did so and REx managed to slam a fist hard into the side of his face before the face of the shield struck him hard in the side and sent him sprawling. If Mercer had been at full strength then the face of the shield would have erupted in spikes, ending Rex'es part in the battle. As it was, it remained craggy and relatively flat faced. Mercer massaged the side of his face where Rex'es punch had left quite a dent, then converted that hand to a whipfist and launched it at Rex while he was on the ground.
"You shouldn't have done that." He snarled as he did so. Meanwhile, Holly threw more bombs at the turret, follwed by a flashbang to blind whatever minions might try to attack her while Mercer was occupied.
OOC: @Demon Archimedes must have incredible reflexes, considering that Jensen has already tackled him and is within melee range, making it nearly impossible to draw a pistol.
Archimedes managed to get off a snapshot that struck the side of Jensen's armour and sizzled across the surface before Jensen smashed into him. He slapped the plasma pistols from Arch's hands, before straddling him on the ground and bringing his arms up behind his head and extending his blades from his elbows, ready to strike down through his opponent's ribcage.
