If you enjoy tower defense, this is one is turning into a classic. The towers and physics are well done and there are subtle nuances that the detail-oriented strategy player will enjoy. Every few months more and more free content gets added, although today there is enough maps and a dozen various types of challenge modes each to last any one player for hours. The character and story are better than average too, this game is well worth a few dollars.

Just to give an idea of how this game was designed.... controls can not be modified from the main menu, only from within missions! Pausing in a mission means the user can't navigate the menus. Therefore, the only time someone can modify key or joystick commands is during a live mission, and it's not a simple process. This is only compounded by the fact that none of the keys are mapped to the commands listed in the various X3 guides.

All in all, I really can't recommend this game at all. I had high hopes for it, but this is nothing like Freespace or the iconic Tie Fighter games. Even Xwing vs Tie Fighter had more in-depth ship systems management, this game seems focused on everything outside the ship. Turned into a big let down. And to believe, more DLC and a series reboot X: Rebirth is coming out soon...

Silly, addicting little game! Surprisingly well-designed for a freebie, and unlike most F2P games players don't need to spend a dime to play the later levels.
