King Art Games have released their second alpha build for their upcoming alternate history RTS, Iron Harvest.

This new build marks the first time that testers can play multiplayer, in either co-op or competitive 1v1 and 2v2 formats. Other new features include five new mechs, a new weapon system, upgradable buildings, a improved cover system, fortifications, melee combat, and more.

You can find a new trailer above. Kickstarter backers at the $55 level should already have access to the latest build of the alpha.

Here’s a rundown on the game, via King Art:

“After World War 1 farmers found a plethora of unexploded ordnance, barbed wire, weapons, shrapnel and bullets while ploughing their fields. They called it the Iron Harvest.”

Iron Harvest is a real-time strategy game (RTS) for Playstation 4, Xbox One and PC, set in the alternate reality of 1920+.

You lead hero characters, mechs, and soldiers into battle. Cover mechanics and dynamic destruction play a major role in combat. Your squads take cover automatically, but a simple brick wall will only offer protection against small calibers, not against mech-mounted cannons.

Throughout its open sandbox levels you have to find your own way to reach the goals set by the dynamic story line. 1920+ was developed by Polish artist Jakub Różalski and earned him a cult-following because of his beautiful artworks painted in the style of the old masters..

The game takes place in the world of 1920+, an alternate version of our own world where mankind, fascinated by technology, engines and iron, invented powerful walking machines. Once mighty weapons on the battlefields of the Great War, they are now part of everyday life.

Mighty factions fight for influence, while hidden forces are working towards the destabilization of Europe, determined to set the world on fire once again.

• The Polania Republic is a large agricultural country with a long history. It is trying to maintain its status and territory, struggling with its aggressive neighbors: The Saxony Empire in the west and Rusviet in the east. Polania initiated a program to modernize its army while a large part of the country is still occupied by Rusviet forces.
• Rusviet Rusviet is huge, powerful, and has unmatched industrial and population potential. However, the country is tired and worn out by the long war. People are frustrated, and the power of Tsar Nikolaj weakens. Mysterious Grigori Rasputin has become an extraordinarily powerful man and revolution is in the air…

Iron Harvest is currently in development for PC, PlayStation 4, and Xbox One.
