You'll have to play through a bit of Guild 01 before you can sample Time Travelers.

Level-5 has bundled a demo of Time Travelers with Guild 01. But you're going to have do just a bit of work to unlock it.

The Time Traveler demo will become available when you've done the following in the four Guild 01 games:

• Liberation Girl: Clear story mode in any difficulty
• Rental Weapon Shop: Pass the 15 day mark
• Airporter: Make your airport into an international airport
• Crimson Shroud: Reach the end of an event in the game's second chapter

Do all this, and you'll get an early sampling of Time Travelers, which is due for 3DS, Vita and PSP release on July 12.
