I try to pretend HM2 never happened.
Contracts and HM1 were genius imho, because there was more focus on profesionalism, no bullets, just killing the target type gameplay. Silent Professional rewards, etc.
HM2 felt like it didn't know what it was, a sequel to HM1 or a James Bondesque Action Game. It plays more like Freedom Fighters with so much 3rd person combat then the sneak and assasinate play of HM1 & 3. I'm hoping 4 plays like 1 & 3. Lots of attention to detail in the levels, multiple paths, and no forced fights.
