Battle Engine Aquila is a good looking and simple game which could have been much better.
The mission editor is set up in a unique way giving you scores for levels and the ability to go back at any time and play any mission. The mission path even branches out on occasion offering you the option to play standard difficulty missions or much more difficult missions. For each mission you will have the choice of 1-3 mechs and also the ability to chose from among several wingmen all of whom have different strengths and weaknesses(this will come in to play depending on the type of mission).
I never heard anything about this game and saw it @ a used book store for $4 so I thought I would give it a try. I have to admit I was surprised how much fun it was to play. well worth the $4. I even managed to get stuck on a couple missions and had to resort to going online and finding a walkthrough.
There isn't really multiplayer, just the ability to play someone else on the same computer with a split screen(annoying). Online could have had potentional: either pvp or even better co-op against the AI in randomly generated scenarios.
