I tried Jack on Clocktower. LT shoots Gnasher. RT shoots Lancer but it’s inaccurate. I couldn’t hard aim at all. The Gnasher seemed okay at point blank range, The Lancer sucks because couldn’t aim it anyway. Couldn’t reload either. Couldn’t get more bullets from ammo box. But I could pick up random weapons and ammo boxes off the ground. When I had Gnasher equipped, holding RT seemed to switch weapon to Lancer and shoot, and vice versa. Overall, it’s not great. Couldn’t get more bullets for either weapons, but I could Cloak I think. I could boost and fly faster, and I don’t think going into next wave gave more bullets either. There is no cards equipped when loading in, just like expected. It’s not possible to rev chainsaw as Jack. Zapper and heal beam don’t work on Jack either, probably intended. I couldn’t switch Gnasher + Lancer for other weapons. It would just pick them up, so three weapons altogether.
