From April 1st till April 25th engage in the battle for resources on the desert planet, populated by giant sandworms! Fantastic combat machines of the future, bright new location and awesome prizes will make your eyes glow!
From April 1st 09:00 GMT till April 25th 11:00 GMT The desert planet is so beautiful when the sun is low. Rolling over the sands, you can see cinnamon in the air, the most important resource in the known universe. Two mighty houses fight for control of the cinnamon fields - the House of the Bull, ruled by tyrannical Mister Paejeh, and the armored corps of the imperial aristocrates, the House of the Hawk, new governors of the planet. Cinnamon fields are the home of gargantuan sand worms, revered by the local population as divine beasts known as Fathers of the Desert. The worms make dangerous harvesting in the desert deadly. Roars of engines and rolling over the sand cause sandworms to attack harvesters and escorting combat vehicles. Father of the Desert comes to punish noisy neighbors!

The mission objective is to achieve control over three key points in the desert location. The Houses of the Bull and Hawk use the same imperial combat vehicles, but each House has its own unique combat unit. Proceed with extreme caution! Firing guns and moving at high speed attracts the sand worm!
