First of all, please ignore k2fnm64 's review. He or she has clearly failed to check out this game before parting cash and hasnt even stated WHY it wasnt something they liked. If you are looking for Call of Duty with aliens, you will not find it here.
Its very rare I'm compelled to leave a review but this is a game many will miss out on..
What you have here is a solid strategy game with turn based combat.
Out of battle - you manage your base and resources, do I spend my resources on better armour or does my squad really need plasma rifles more? Juggling your resources are key here.
In battle, you take turns to manoeuvres your squad, to outflank the enemy or even ambush them . You have 4 classes of soldier - sniper, assault, support and heavy. You will gain abilities and powers for your squad dependant on these. There are scores of different types of enemies to deal with and tactics suitable to dealing with them. The AI is smart though. They will corner you and pick your soldiers off if you're not careful.
The developers have really made looking after your squad vital, you cant afford to throw soldiers away, especially on the higher difficulty levels. It really is heart wrenching when your best assault colonel gets taken down.
There are a few minor niggles that prevent this being a 5 star game.
There is a frame rate issues when there are lots on screen or in a complex building. I think this is less of a problem on PC maybe. Also sometimes the camera can get a bit confusing on multilevel levels. Additionally the game has a tendency to freeze from time to time.
Enjoyable and rewarding gameplay
