Bethesda has dropped a new trailer for Dishonored this morning and it's a pretty entertaining watch, offering a few examples of ways the player can creatively dispatch enemies. They mostly focus on using combinations of powers, though a bit at the end demonstrates the practicality of force pushing enemies into electrified barriers.
I like what I'm seeing here, for the most part, but I do think it's a little weird to summon a swarm of rats to single one out, strap an explosive to its back and then take possession of its body to guide into enemies. Especially when the exact same results can be achieved more elegantly by bending time as an enemy takes aim, then taking possession of them and moving them into the path of the attack.
Or, you know, just siccing the rats on them. That'd probably work too.
