I hated the battle in the flying cargo jet halfway through code veronica. It was the hardest part, and I had to do it without dying to get that A ranking, which resulted in me starting over quite a bit before I got it right. Also, the invisible boss in RE4 you fight in the small corridor, hated that one as well, but I think I eventually found a trick to it.[/quote]
If it's the boss I'm thinking, it's the one you can either fight or not fight, and if you do fight it, you can use like the air canisters to freeze it
amirite
Yup. also, if it wasn't for the strategy guide I would've NEVER beat the sliding puzzle with Ashley.
Another thing on the topic of IoG, I liked it, but I did get stuck for 5 years(I tried for like 4 days straight, and came back to it several YEARS later) in that damned "vine" dungeon. It looked way too same-y to not get lost, unless you do it in one run.
One last thing: RE2, when I first played it in 2002 (first time I played it), I got stuck at the damned gator. I didn't find out about the air tank until I looked it up online.
