Gundeck is a Tinker with a focus on heavy artillery. He has been seen using missiles and guns large enough to fit on a tank. He has a back mounted rocket that he can use to move around. He has tinkertech that allows him to easily reload his weaponry.
Gundeck also has a Brute power that gives him super strength, without any additional durability.
↑ 1.01.1Gundeck and Solarstare entered, with Rain among the half-dozen people who were right behind them. Gundeck was a big guy, loaded down with his weapons, but even though his power left him able and ready to carry a whole arsenal with him without buckling, he moved like a burdened man. - Excerpt from Breaking 14.2
↑Gundeck hefted two guns very much like what I’d envisioned getting when I’d asked for weapons. Each looked like it could be mounted on a tank or boat, barrels telescoping out to a full ten feet in length, with gaps for venting along the sides. - Excerpt from Radiation 18.6
↑Gundeck used a back-mounted rocket to get back and away. Oberon pushed over the building, and in the process, collided with Damsel. She’d been within the upper floor of the building, using her power to hold and contain a large sphere of the annihilation energy. - Excerpt from Radiation 18.6
↑Tinkertech reloaded his weapons as he let mechanical arms pull them back, and he let one beefy, armored mechanical arm hand him a shorter firearm. He had enhanced strength, but not enhanced durability, so he leveraged most of that strength carrying his military inspired tinker weapons. The mover that was helping him get around the battlefield perched nearby, looking nervous. - Excerpt from Radiation 18.6
