3 Minecraft Style Sci-fi Vehicles

We are in need of 3 rigged and animated models for an upcoming game. The game uses an art style similar to Minecraft and will therefore be relatively simple. The artist must be able to balance simplicity and beauty in their design. The three models required are: - Mech style vehicle - Hover Bike type vehicle - Hover Tank type vehicle Animations will be required for each of the following actions: - Move forward - Move backward - Move left - Move right - Attack - Jump (mech only) Models and their associated rig and animations must be output for seamless use in Unity 3D.
