Since the game is now free and the download and doesn't take up much space on your hard drive you should just try it. Its a fun game that can keep you entertained for a few hours. The company that made the game closed down when they made the game free, so if you happen to get one of the game breaking bugs that some people in other reviews metion, then unfortunately there won't be any fix for the game. Other than that, the game is really solid, although there is not that much content.

The design of the game is really simple, but it also surprisingly deep. You have access to 4 types of units that have distinct roles and I found it necessary to make all of them in every game. It's not the lazy kind of RTS where every unit does the same thing just with more health and/or damage.

The gameplay is really well thought out and balanced. The goal of the game is to capture 75 percent of the territory on the map, which you do by using your Sentinal unit. The sentinal can capture territory and structures by moving over it, but it cannot attack or move through enemy units (or be killed/damaged). This means you have to use other units to attack enemy units and clear pathways, as well as block the enemy sentinal from moving through territory, at least until they send units to attack yours.

The multiplayer seems to have been shut down and does not work anymore unfortuately, so the only content left is the campaign and skirmish missions. The expert difficulty ai, which is the highest level ai in skirmish mode, is a decent challenge and can easily exploit your mistakes. You have to manipulate the ai into do something stupid if you want to beat the expert ai, especially if you give yourself one of the handicaps. One tip i can give is if you get the AI stuck in a game of chicken, where both sentinals are right next to each other and waiting for the other to move, use that time to gain an advantage. Play passively at that point to avoid provoking it into moving and get units like snipers that you can use to cause attrition to the AI's units. You can go back on the offensive once you've built up units and created a winning position.
