The first game of the best tower defense series!! – Sentinel: Mars Defense Review

Let me start off by saying I started on the sequel. While not as great as the sequel, it is still just as much fun. I do miss the extra upgrading but it is the first game in the trilogy after all. If you have an extra dollar lying around, get Sentinel 2, but if you have $2, get this and the sequel. Both are worth every penny!
