Cut Friendly Unit#
A class definition file for an alternate version of the AAT tank exists, going by the name "caatcaptured". If spawned into the game, its affiliation is revealed to be Friendly, which makes sense given its name. It only gets used in an early version of this mission's script - island2-2.wrl. Judging from unused voice lines from this mission, it seems there were going to be "guard vessels" protecting each Demolition Boat. These captured tanks could've been those guard vessels.

Unused Audio#
Think there's a lot of enemies in this mission already? Consider yourself lucky, there was going to be WAY more.
Possibly an unused intro to the level.
Originally the enemy bombers and fighters would have come from a carrier. In the final release, they just appear in the sky. Note that the first audio clip is used.
Remember the HAG enemies from the previous game? They would have made a return in this level.
A bunch of remarks from Nym and Jinkins about "guard vessels" assigned to the Demolition Boats for extra protection. An unused friendly unit exists that could've been used for this purpose, as shown above.
An irrelevant conversation about the sensor station. Adi was briefed on what it did earlier.
An alternate version of the "split up and go around the island" conversation. Also the sensor station was harder to find.
An alternate take of Nym's "I don't like being spied on, Ruuk."
This would've been said by Nym after the sensor station explodes.
Unused taunts Nym would say to Ruuk during the boss battle.
Unused taunts Ruuk would say to Nym during and after the boss battle.
Remember the Lok Revenants - Nym's old crew - in the first game? Audio files from this mission and a few others show that they would've returned in this game to help out in various missions. They were ultimately replaced by the Mere. This character, known internally as "NP13" (likely Nym Pilot 13, with his own unused communicator head) originally took the place of Sol Sixxa, as he did not exist at some point in development. One of Sol Sixxa's demolition boat hull damage lines accidentally goes unused as an NP13 line never got replaced. You'll see more unused voice lines from Nym's old crew in later missions.
This line from Jinkins could possibly be from an unused mission outro. It would've also given context about why they're heading to Mount Merakan.
