Developers Hexage have created a fantastic RPG style game which is available to play in high definition on Android devices. Robotek HD is based on a world campaign where you must win and take over nodes scattered across the world map.
Each node is marked with a difficulty factor and the “power” required to enter each. Robotek allows you to start with 50 power points, and more can be earned along the way together with experience points as you defeat nodes. As you would expect the more challenging the node the more points and experience you can win. Watch the video after the jump to see it in action and give you a feel for the style of graphics you will get.
Robotek is currently free to download but does contain in game payment options if you require to recharge node to gain power back. But the entire game can be completed without spending anything if you have the skills.
