Fallen Haven 2
Liberation Day is the sequel to Interactive Magic's previous release Fallen Haven. A tactical combat game with strategic management elements and an isometric perspective, this game also bears a strong resemblance to X-Com. Oh yeah, and the enemy is familiar as well: aliens!
There are five continents to be rescued, each broken up into several provinces which are the settings the tactical missions. The overall strategic challenge comes in anticipating the mission's set objective and the number of turns needed to complete it. After an initial deployment phase, the missions just consist of the usual alternating movement turns between you and the aliens.
You have various units with differing armor and weaponry and you can call in different troops, air attack planes, and other units on each turn. Successfully completing a mission gives you industrial credits, which you can use to create buildings and defenses for your Earth HQ. Your forces can be upgraded by capturing a Tech Lab during a mission and exceptional types of troops, such as Special Ops, can be deployed from time to time.
If you like strategy games, you will like Liberation Day, and you will be challenged. The interface is easy to learn, but there is a lot that you will grow into using. At first you will not need all the features to succeed, but each level you go up you will need to use all you have to finish the objective. Liberation Day is a game you can dive into, where it cannot be finished in one sitting or even a weekend.
