RE 4 Question

I just completed RE 4 for the first time. Unlocked Mercenaries and the Ada Adventure.

Just wondering if there are any more unlockables if you go through the game a second time. I'll probably play through it again anyways but just was curious if there arwe any more surprises or if this is it.

Thanks.

There's nothing left to unlock, but finishing the game onceunlocks more than just those2 modes.Select the main game andyou'll notice that you are able to change difficulty settings and costumes.
