Helios and the Spartan
City Siege 4: Alien Siege
Clear Vision 1
MegaCity was my attempt at building something fun and original, but that required at least some thinking to play.
Not the thinking as in 'this is hard work' thinking, but in a 'this is fun because I have to think about this, not just push buttons' kinda way.
Logic and planning ahead is what's needed for a high score in MegaCity.
If you really like this little version, there's also a more in-depth version with new building unlocks etc available for iOS and coming soon to Android and XBLIG. Check out here for more info: http://colepowered.com/?p age_id=6
