Factual error: Items in this game such as chairs and keyboards will explode with deadly force when shot with regular guns.
Factual error: Bullet holes by all guns look the same. Even the Watch Laser and Moonraker Laser make bullet holes identical to other guns. The Tazer even makes bullet holes.
Bug: If the player uses invincibility cheat on Silo level and sets off a plastique or let the one minute timer run out, a huge fireball will follow Bond from then on. This will even kill any enemy Bond is passing by.
Trivia: The Aztec level can be beaten without killing Jaws and without even operating the open/close exhausting bay terminal. If Bond attracts the yellow jump-suited guards in the corridor between the room with the terminal behind the glass doors and the exhaust bay and returns to the room and hides in the back, it's possible that the guards will open the glass doors and Bond can use the guidance data and recover the launch protocol and finish the mission in any place within the level (even in the exhaust bay). Whether this is a glitch or deliberately made by the developers is not known.
Chosen answer: In normal gameplay, yes, this is the only level where you can dual wield two different weapons.

The question was why is this the only level that two different guns can be held. Not is it the only level where guns can be held?
Thank you. Though it doesn't really matter now. I asked this question like 12 years ago in 2013, when I was still in my early 20s and didn't know anything about game design. I fully understand this now.
