AirRivals is an MMO game that allows you to take control of aircraft in order to complete the missions you are given.
As you progress through the game, you will have to upgrade your aircraft in order to keep up with other players and with their gear so you can defeat them when you go into the arena to battle.
Heavy Weapon Deluxe is a 2D shooter game where you control a very advanced tank. The objective is to blow things out of the sky, mainly, in around 20 missions and two game-play modes. With good graphics and sounds that complement the game-play, this game is very complete. But a price tag that high is bound to make your wallet think a bit about the game.
