It is an all PVP game, where you build up / train / equip an army and send it to pillage your foes. It is currently in open beta right now, and is accepting players.
It is completely free to play.
Basically, it's a text-based browser game. It's all PVP. You get some citizens everyday, you can put them to work as: Miner, Soldier, Guard. You can equip your army with different weapons and armor. You can also supplement your main army with Hellpigs( they are not equippable, and are worth a set att/def value) they are cheap but die easily in combat. You also have a set of skills that you can upgrade, these will either upgrade your attack/defense, upgrade the amount of citizens you get on a daily basis, etc.
x-fire web game detection is set up.
There is also a referral - reward system, where you can get free in-game cash and citizens for referring your friends to play.
It's a great time-waster. You can get online and play for about 10-15 mins, about twice daily and keep up with the rest of the players.
A whole bunch of updates have just been added to the game. There is a auction house, new troop types, a recovery ward (to save your soldiers injured in battle), participation points (you earn free in-game items for particiating in the fourms, etc.) Multiple battle strategies, etc.
The game is growing by the minute. Come cement your place.
