Complete game w/o going back to a level? That's nigh on impossible.... Maybe to get to the end, but not past it. Well, I guess, if you just screwed around and shot arrows all day and never tried to finish a level... it might be possible... But really time consuming and pointless.
Meh. Okay, the Super Secret organization that I work for has it's name on the front of it's building? And my parking spot is labled Agent Jake? No one could possibly figure out who we are!
That said, needed something more. I thought the music with the pointing was actually kind of funny. But in the end it was just too easy. The "Grand Finale" consists of you shooting a guard in the front of a highly secure building... (Really bad plan) and then watching a movie... bleh.
This is actually really easy once you figure it out. I was horrible my first two tries, but then ended with 60 lives my third try.
The key is to go to the far right corner and drop a lot of guys at once. (Try and aim... don't just drop.) If you hit it right you can get upwards of 6 guys into a single truck. Don't be afraid of some dying... that's what they're there for. When it gets harder you'll have to wait in the far left corner until the chainsaw buzzes over there. Then wait for the lazer to fire, then head over the the far right corner again. Easy Peasy.
