The main idea behind Meatshields is that players have many games going-on simultaneously and take their turns regularly throughout the day rather than playing a whole game in one sitting. The game can be played from any browser, so you can take your turns at home, on the bus, or at work!
It has a full tutorial and AI to practice against before fighting real opponents :)
