That second level with the military is intense. You really have to be on top of your aim to get through it. But this was a neat game, it reminded me a bit of that arcade shooter where you go through the mansion, just without being on rails.
You can use the med box to heal and the ammo box to get ammo. However you have to find them. Hint: They are near the elevator. It makes the level a lot easier :)
I did use them (well, the heal.) I still found it very challenging. I did use it only once per attempt, I don't know if I was supposed to be able to re-use it?
