The one of the most undervalued games made by russian gamedev, in my opinion.
Good story, stylish design, great music, big open world with own secrets.
The game about Artificial Intelligence, enclosed in small indestructible ball, which controls a large battle machines, designed to exterminate all what it considers as enemy.
But these robots doesnt want to kill all humans, it's too mainstream, moreover they would worship humans if they had them on their abandoned planet. But no one forbids them to fight each other. Or to trade. Or to be a courier.
I strictly recommend you to also to play the first part of this game (AIM, 2004). In some aspects, it better than this part, better story, in particular. Sadly, we can't buy it on Steam.
On the other side - this game is a bit buggy. But i hope, it will be fixed in future.
