Tiberius had moved up with Aegon and Vella, he was currently using a fallen support pillar as cover the best he could, which for someone the size of him he had to almost lay down against it. Now if this pillar was still upright it would be perfect for him, gripping his Phaeston he pied around the corner and opened up with two small bursts on a pair of Cerberus assault troopers that had gotten quite close to him, both bursts hit there mark and the troopers when down clutching the wounds on their legs, it was more to disable them than to eliminate. Beyond them the Turian watched Ellis completely eradicate a guardian before being consumed by the smoke, shaking his head slightly Tiberius had the look if distaste hidden behind his black visor, the thought of him being Ex-Cerberus still bothered him that and the fact he didn't seem to follow order at all.
"Erecting a Biotic Barrier, requesting biotic assistance!" He heard Vella call out over the comms, "On my way" He called before getting up and moving closer to Vella, he noted the lack of cover "Spirits, Gonna have to risk it" he muttered as he neared and found some firm footing as he stopped out in the open of the enemy view. A blue hue formed around him before he cast a barrier around himself for extra protection, while casting a second around Vella's barrier to reinforce it. Tiberius watched as Rykarn took out what looked to be a grenade launcher and begin to fire it into the crowd Cerberus, he could only imagine the destructive power of a weapon like that 'I have to get me one of those' he thought as a grin formed slightly on his face.
"Barrier Reinforced" He called out and with that didn't take long before he started to feel the affects as he breaths quickened, one barrier was not really a problem for him but two was slowly proving to be a bit of a challenge as he felt his energy drain away from him 'Come on detonate already' He thought as then the grin he had faded as he watched the YMIR mech come into his view 'Great, just what I needed' he thought than braced himself slightly as it's mounted rotary cannon began to opened up onto the barrier around him. He could only hope it would stop and reload or be taken care of by the time he would be forced to drop his barrier, as he currently concentrated on keeping both barriers up. "We need to take that thing out!" he called out over all his teams channels.
