Agreed on turrets, but to be honest, I think the game would be too hard for me otherwise.
I felt like I was really just grinding the prison until I managed to just start going nuts on turrets and traps. Now I’ve cleared like three or four different areas on the first go, beat the first boss on the first go, and am getting pretty close to the second boss. The combination of the traps that stick an enemy in one place and the turrets is pretty godly.
