Operation: Polygon Storm - Deliberate Force Pack DLC

A single map that adds a bit of variety to the game with the train track mechanism, as well as a great way to support the developers behind the game. The map is a bit more challenging than the previous ones because of the mechanism, but still completely doable even at the highest difficulty. For the price it is at the time of posting this review, it is perfectly appropriate and, in my opinion, worth buying.
