Finally! I that horrific GTA: Vice City Stories mission that I've been pounding my head against. I think I must've tried it upwards of 30 times, and eventually resorted to researching (thanks GameFAQs!) which side activities would boost my combat stats so I could survive a little longer. A little bit of Air Rescue helicopter grinding later, +50% health and many, many, many tried at the mission got me through it. It didn't help that after the painful pathing + camera firefight there was a whole final section which, while back to good GTA gameplay, was hard enough that I could complete the annoying stage and still fail the mission.
Sure, I could have just resorted to a cheat code, but I'm ultimately glad I didn't. I'm enough of a GTA addict that I really still do want to complete the game (hey, it's got to last me until October), and I think if I'd crossed that line into out and out cheat codes it would have lessened the experience. It may be academic, but there's a bright line to me between focusing on a minigame to increase my health and using a cheat code to just be plain invincible.
