The Big One (SR-71 Blackbird Weapon Pack)
You have to finish the Ace bonus objective for the final mission (Mission 4.5-Final Count Down) to unlock the SR-71 Blackbird's fourth weapon pack. This weapon pack includes the game's super weapon, the A-SLAMR. The A-SLAMR does not recharge once fired so use it wisely. Note: Both the SR-71 Blackbird plane and "The Big One" weapon pack can both be unlocked at the same time if playing under the Ace difficulty setting. Just complete both of the required bonus objectives to unlock the SR-71 and "The Big One" weapon pack together (instead of separately).
