"Planets Under Attack" is an addictive little time consumer that reminds me somehow of "Megalomania", because it's gameplay is mainly focused on massive realtime tactical movement of your units between different positions. The different positions in this game here are the many different planets scattered around each map in the huge campaign mode. After playing a bit into the game you can even begin to set different types of planets, one for the bank (it produces money), some for battle planets (they function as big defensive artillery bases ... well ... sort of) and the rest for breeding more men and producing taxes.
There are three different classes to play in this game, although until now - except the robot tutorial mission at the beginning - I've only played the human species so far. But it's clear from the campaign matches and the many hints in the manual that they even have different play styles. Robots for examples don't collect taxes, they use their bodies to upgrade planets and so on ...
This game features deep tactical decisions lying under a neat and easy to lern point and click interface. Most of the time you have to act under pressure, be it time that runs against you or enemies attacking your reaches of space. There are many different mission types during the campaign (or in local / online multiplayer) only interrupted every so often for a special boss battle stages that can differ from the normal gameplay by various intriguing ideas ... but I don't want to spoil you here ... ;)
So whats left to say for me is that this is one of these mostly overseen strategy pearls you in theory just can play for a break during yourr office work. The only thing is, this game gets so amazingly addictive in a very short while, you better tell your boss it could take a while for him to see you again ... :)
In my oppinion you should totally get this game. It's fast, it's deeper in strategy than it looks and it's fun either in small bites or equally for a couple of hours at a time. Give it a try and at least download the demo. And if you tend to like the game (like I do - just in case you didn't mention yet), maybe we could get together sometime and meet up for a few online matches as this game really deserves full servers.
