Screen 14
The second level (but in the game Ethan wears a different suit)

Screen 15
??? Maybe it’s the hallway to exit from the KGB

Screen 16
The embassy (but the Lenin’s statue is missing)

Screen 17
Head Security Officer’s room as in the game (but the suit is different, just as RagingD said, and Ethan looks more Tom Cruise than in the game)

Screen 18
It seems a beta embassy’s room because the door and the plants are the same of the game). Or it could be a totally different level missing in th game.

Screen 19
The secret room in the KGB as in the game

Screen 20
it seems the entry to that beta-embassy. (the hud is totally different)

Screen 22
It’s probably a beta first level

Screen 23
First level

Screen 24
It could be a beta version of the escaping level from the KGB HQ

Screen 25
A beta version of the Head Security Officer’s room

Screen 26
Maybe is a beta version of the escaping level from the KGB HQ (but the enemy is totally different from the one in the game)

Screen 29
The bathroom in the embassy and the Deputy Ambassador (but the mirrors don’t reflect in the n64 version)

Screen 30

I hope that was helpful, and sorry my bad English xd
I’m also working on a hi-texure pack for the N64 version of the game and i’m restoring some beta stuff (Ethan smoking and the hud xd)
When I’ll finish to mod the game I’ll inform you. Bye!

This level only ends up being a cutscene in the final version.

The wet suit is not in the final version

This suit is changed from white to red in the final version
