Apparently if you press all 4 shoulder buttons at the same time in the main menu, you will have access to a free demo of Sly 2 in Up Your Arsenal.
Hold L1+L2+R1+R2.
For those who have a copy of this Ratchet title will have a chance to play a small demo of Sly 2, Bands of Thieves. It's also funny that I didn't realize the demo was mentioned in the game manual.
Did anyone knew about this when they purchased a copy of Up Your Arsenal?
If so, was the demo fun overall?
If the cheat somehow doesn't work on you, try other game site sources that might have the accurate explanation of doing it.
