Transformers (Glu)

Transformers by Glu is a mobile phone game produced in 2007 based on the live-action movie.

Plot

Optimus Prime was damaged and separated from the Autobots on his arrival on Earth and is now stranded in the Hoover Dam. Unable to risk their communications being detected, Bumblebee sends out a signal that reformats your cell phone to send and receive Cybertronian signals! Optimus Prime's systems are a bit scrambled, so you'll have to guide him through the dam- and beyond- until he recovers!

Mobile Tracker Units

Decepticon drones.

Purple "Light" drone These lightweight Decepticon drones are the first enemies you encounter in the game. They are easily dispatched with either blaster fire or hand-to-hand combat.
Aqua "Medium" drone These middleweight Decepticon drones can absorb several barrages of blaster fire and are more easily dispatched via brief violent bouts of hand-to-hand combat. They can be quite dangerous if pinned between two of them. Equipped with a sparking short-range blast.
Orange "Headbanger" drone These hot-running miswired drones can fire long-range fire blasts, but only the horizontal plane of the level they're standing on. They are extremely resistant to small-arms fire, but an aggressive physical offense will force them to abandon their fireball attacks. The headbangers don't seems to be properly insulated against their own internal heat, as evidenced by their signature spastic short-out after firing.
Orange shield drone The drone's shield protects it from your blaster and most of your attacks. Block its attacks until it performs a two-handed strike (lettin go of its shield to do so) then attack.
Orange "Gunner" drone This drone is usually found in elevated positions taking pot-shots at you. Fortunately, it's particularly susceptible to blaster fire, switch to it as your target and remove it from the battlefield before you have to get close. A nasty customer in a direct physical confrontation.
Green "Bruiser" drone These heavily-armored drones are skrug off blaster fire and most attacks. What's worse, their stunning attack can trap you within reach, allowing them to pound on you again and again. Rush these units with a dash attack to throw them off balance, then lay intot hem with your fists.
Blue "Flashfist" drone Thee thoroughly nasty drones will kick your aft six ways to Cybertron. They shrug off weapons fire (though it can hold them in place) and almost all physical attacks. Their punishing short range energy attacks deliver crippling damage even if you block them. However in the moment before their block-breaking attack, when both fists are raised in the air and flash, they are vulnerable. Even then they're too quick to let you get off a full combo, destroyign them requires multiple attacks. Frequently deployed in quantity, do not under any circumstances allow yourself to be trapped between two of them.
