Three lite versions of games we enjoyed were all released recently. If you don't yet own these games, you really should at least give the lite a spin.
Like the original game, the goal of Labyrinth 2 is to get the silver ball from the starting point to the goal while navigating walls and avoiding the holes. In the first version, that was pretty much all there was to it. Labyrinth 2, however, adds a number of new elements that graduate the game from simple wooden toy simulator to arcade game.
These elements include cannons, bumpers, doors/switches, magnets, fans, resizers, merry-go-round, duplicators, lasers and more. Navigating the levels still require careful tilt control to avoid falling to your death, but are also more puzzle/goal driven as you must also figure out how to make it to the exit. Levels are timed as before so beating your individual high scores remains the motivator to play a level again. This time, however, they've added a ghost ball representation of your best time for you to directly compete against.
Heavy Mach 2 Lite (Full: $2.99) - A great sequel of the original Heavy Mach that we liked in our review, Heavy Mach 2 shifts the perspective to an overhead view and adds all kinds of new goodies.
Gameplay in Heavy Mach 2 consists of taking various missions that seem to either have you killing things or collecting things, going out in to the battlefield to fight with your tank and returning with your spoils. As you earn credits and experience by defeating other tanks and completing missions, you can eventually buy tons of weaponry and different upgrades to your tank as you level up.
Call of Duty: World at War: Zombies Lite (Full: $9.99) - The zombie survival mode from Call of Duty: World at War compacted on to the iPhone. We thought the game was really cool when we got our first look at it.
The game begins with you in a house with boarded up windows. Waves of zombies slowly start attacking and you need to defend against their attacks. Windows are repaired with the press of a button, though having your attention split across the different entrances is a challenge. The ramp up is rather slow, but soon you'll have trouble surviving the oncoming hoard of zombies. As you kill zombies, you earn coins which can be used to buy better weapons which are found throughout the structure.
