A few small alterations to improve the game.
You have a mission: find the spies and secret items before your time runs out!
Your mission takes you to major cities around the world. Spies wander around freely, so the spy intelligence display within the game is essential for learning about sightings in different cities. At higher levels, even if you do find the spy you have been tracking down, that spy will sometimes elude capture at the last minute, escaping to a neighboring city.
Like any good treasure hunt, Global Spy also requires you to locate the secret items mentioned in your mission briefing. Unlike spies, these secret items don't change location once the mission starts. There are between two and five spies per mission, and a corresponding number of secret items.
Tip: You often have to plan the shortest route to a specific city. For example, you may be in Singapore when the spy intelligence display tells you that your current target, Prof Santos, has been spotted in Buenos Aires. You have to get there quickly, or he will move somewhere else. Having a working knowledge of world geography will certainly help you plan your route, but you may also find the in-game map helpful.
The first three levels of Global Spy are free, but an in-app purchase gets you a Super Spy Pack with 27 more levels, new spies, new secrets and new challenges.
This fun game is also good training for your brain -- it develops your skills in memory, real-time filtering of multiple information sources and efficient route planning.
Go get them, Super Spy.
