Harvest Massive Encounter

An awsome game made by a swedish group Oxeye Game Studio, www.oxeyegames.com

Its currently in open beta till end of October, go have a try!

A tower defense game at the core but enemies approach en masse without a defined route. Map expands indefinitely as your base grow.

Solar Generators to power the base,
Ore miners to extract resources to exchange for credits
Energy Nodes help transport energy all around the base
Laser Towers as basic defense, you can link towers together for greater damage and range
Missile silo; can be upgraded to either long range missiles or cluster bomb missiles.

The game is deceptively simple but very addictive to play.

They're looking for people to carry the game and its definitely a game Man!festo should have in the library!
