Right now I am creating three new uncommon towers for Metropolis! This will allow a few more starting strategies in the next release. Right now with just Rabbit, Beaver and Dandelion the start of the game is a little bit boring.
Hitman is a classical sniper. He has a long range, a long cooldown and a high damage with a slightly improved chance to crit.
And no, the Electric Chair does not account the Hitman to be a crimical right now 🙂 So no electro shocks towards this allied tower. It would allow for interesting strategies, though.
