Skarr took some brief happiness in doing something that even the crazed Asari thought was off. It was an odd thing, to see him grin. He usually had such a cold demeanor. Anyhow, he knew if his plan of pushing the grenades at the enemy did not work, it wouldn't falter the odd plan the other biotics were already enacting, so why not do it? Most didn't understand that Shockwave wasn't a series of explosions, but intense pressures. 

Either way, everything went to Hell next. The Big veteran was considering the advice of the younger Krogan, though the reason Skarr did not shout it out was simple. He'd been desensitized to how teammates would react after centuries. He guessed it was all of those Vorcha and Batarians he'd fought beside, but most would never listen to orders. Good thing some of these teammates seemed to. He followed suit mechanically, making sure his weapons were reloaded and getting all of the thermal packs he could. 

"By the Clans!" Skarr called as the Husks began streaming in. The explosions and rupturing ceiling he was used to, but the Husks he'd not expected to see again. He remembered them all too well. They weren't destructible, and he'd prove it yet again. He aided in the firing of the turrets and Husks with his Assault rifle, but his main addition to the effort was going forward to save that human woman's ass. 

Powerful but controlled, Skarr barrelled forward and knocked over any obstacle or stray and half broken Husk in his way to make it to the fore. With one powerful hand, he grabbed the slim woman by the waist and hauled her up. "This isn't a one warrior show. If you want to keep shooting, hold still." The Krogan lifted her to set bottom on his back hump, her legs able to fall across his massive skull like a makeshift seat. As he guided her up there, he unloaded a shell of his Claymore shotgun into a husk, blowing its fragments everywhere. He slowly backed up with Salissa, who pretty much now had a warmount to fire upon.
