To get the Handcannon you in both PS2 and GC you must unlock all the characters in mercenaries. Also you need to score
60,000 points with every character and on every level.
The chicago typewriter is not so simple to get in PS2. You must beat Seperate ways, and Assignment Ada.
The infinite rocket launcher is easy to get because all that you have to do is beat the game once.
The only hard part about the chicago typewriter, and infinite rocket launcher is that they both cost 1,000,000 pesetas.
The handcannon is free but there is no ammo for this gun in the game. so you have to get the infinite ammo and 99.9 power
upgrade. But all of the upgrades cost a pretty penny so save up!
Quick aim: tired of ganados attacking you from the side and you're too slow to aim in that direction. Well no more, in
the gc version use the c stick to turn the camera in the direction of the enemy. then press the r button to quick aim in that
direction. for PS2 its the right analog stick and r1 button.
