As Rez was reloading by the back door, his face practically dropped from within his helmet as he spotted a grenade plopping down nearby. His armor was good, but explosives were not conductive to maintaining it in the pristine condition that he preferred...well, that was an understatement, honestly. True fear filled his emotions as he began to turn tail and run from the blast radius, squeezing his eyes shut in horror, when the grenade went off and revealed itself, much to his relief, as a simple flash bang that would have been negated by his helmet's visor anyways. He was unable to wipe the beads of sweat from his forehead after that one. Careless. That was unacceptable of him and he got off lucky. Despite them being from a more primitive world, he needed to take this more seriously or else he could suffer some serious injuries the next time something like that happened.
This little diversion cost him a lot of precious time. He grimaced as he finished his reloading and then stormed the building. The survivors were missing, but couldn't have gone out the front with all of the enemies. That just left...
His eyes darted to the staircase. That must be it. However, his attention was forced back to the other enemies, who began firing at him now that he had come into their sight. They had recovered from their own flash bang and were now quite pissed, if their angry shouting and aggressively trying to kill him were any indication.
"Hey, I'm not the one who did that! Shoot the other guys!" He shouted, lifting his weapon and firing back with a wild spray of gunfire out the now nonexistent front doorway. Some of their bullets glanced against his armor in return, chipping away part of his shoulder plate and another shot delivering a painful punch to his right kidney, although the bullet didn't penetrate all the way through.
"That smarts..." he groaned to himself, unleashing the rest of his clip their way in retaliation and to force them to get off of his back for a couple seconds as they scattered for cover or took one of his bullets and hit the sand, far more worse for wear. He reloaded as he quickly traversed the rest of the room, reloading his weapon a second time. Only one more clip after this one and he'd be out his main weapon, plus he was down some clips of his pistols in his previous skirmish with them. Perhaps he'd have to turn to his magical abilities to finish things off before he'd be caught in that predicament.
For now, however, he'd need to use his gun until the opportunity to do otherwise would arise. He took to the stairs, robotic legs easily springing up each one. Once he reached the top and entered a room he was greeted by one of them aiming a pistol his way. Aiming his gun and letting loose a stream of bullets his way, he began backing away to get into a better position of cover.
