Here is a little trivia some of you might not know.

1. Start the game
2. After you enter the Dining Room turn around and go back to the main hall
3. Wesker will send you back in
4. Turn around again and go back to the main hall
5. Wesker will send you back in
6. Character refuses to go back to the main hall
7. Go to Bob - the first Undead (the word zombie is never used in the game, so i call him undead)
8. Inspect Kenneth's Corpse - the Undead has eaten Kenneth's legs, and the two ammo pickups for your pistol are gone. Did the Undead eat them too?

Have fun exploring Resident Evil. The game world is full of wondrous things. Immerse yourself in exploration!

I think at some point there was a flowchart of things like this around online. If you do seemingly unrelated things out of sequence or just slightly in different order, you'll get some weird discrepancies between games. Adds a very minor and weird replayability variable. Kinda glad this nonsense never quite caught on. This is way over the top.
