Did you know that in each level of the game you can get a meadl? destroy a cirtian amount of enemies and you'll get it (also all four piolot must survive). If you get all the medals in the game you'll unlock an expert mode and a sound track and the land master as an option in versus mode. In expert mode if you win a medal on venom 2 (true andross) you'll get a new title screen and you can fight outside of a veicle in versus mode. So far i've got all the medals on expert exept for three.
