Try playing this level with Blast Radius Mod and it's even more challenging at the end area with instant kill Gamma Radiation Cammanders and Freezer commanders to spice things up. Be very careful with Gamma Radiation Cammanders and let the ones bunched up together kill themselves with their own attacks very fun level really enjoyed it. I ran out of ammo for my weapons in the end area. Had to use ammo cheat because I ran out. And you have to watch your health and save often.
