Only one power can be used at any given time. It’s possible to switch between them but not on the fly. You have to actually find a source of that element and absorb it in order to change. Smoke powers are stronger in melee, while Neon powers are more suitable for ranged attacks, with faster and more accurate energy bullets. In the demo the neon element didn’t have a melee attack available yet, but according to the staff at the event it will be implemented in the final game.
Superpowers are not unlimited in their use and don’t recharge over time. It’s necessary to replenish them by observing the surroundings and absorbing energy from the right objects, like a chimney or a car on fire for smoke or a neon sign for neon. Suitable sources are marked on the minimap on the lower right corner of the screen.
There will be other conduits even if their specific elements are unknown. The only one that has been glimpsed uses fire as an attack and can stand in the air by condensing the atmosphere into rock.
There are a myriad of choices and branches that can be followed though different decisions during the game, but there will be only two endings: a good one and an evil one. That said, the path to get there will differ from player to player, and different choices can even influence the difficulty of the game.
