The objective in Warthog Launch is a little odd, it took me a bit to understand the concept at first. Basically you have this Warthog, which is a Jeep-like military vehicle used in the game Halo, and you decide where to position it on the ground.
Next, you have a bunch of grenades that you decide how many of them to put under the Warthog. You also need to position the grenades so that when they explode, they propel the Warthog up in the air to knock out all the floating ...er, uh... things (you probably can tell I've never played Halo). You must knock them all out in a single blast, keeping in mind you may need to use the walls to bounce off of. The game is excellent fun, not to mention very gratifying if you like to blow things up. The animation and sound effects fit the game perfectly and add to the realism of the task. Try it, you'll be hooked.
