Eve Online developer CCP Games and Star Citizen studio Cloud Imperium Games announced they’re collaborating on a new charity event for Extra Life.

The new fundraiser is called Battle of the Bricks, and it will benefit Extra Life, who support the Children’s Miracle Network of hospitals. The live broadcast will feature both teams attempting to assemble ships from each of their space sims with LEGO blocks, while performing wacky challenges picked from spinning a wheel.

While CCP Games will make Eve Online’s Primae ship, and Cloud Imperium is making Star Citizen’s Banu Merchantman ship. Both ships were previously selected via prior fan submissions. The charity fundraising will actually run through December 31, 2022 – via its official site.

“When Cloud Imperium Games gave us the ship-building challenge on Twitter last December, we didn’t hesitate for a second before agreeing,” said Rafn Herlufsen, Director of Player Experience and Community for CCP Games. “CCP Games and Cloud Imperium Games are friendly competitors, and they are similar with their dedicated community of intrepid space explorers. Head live on July 22 to support your favorite team and raise money for a good cause.”

Director of Community for Cloud Imperium Games Tyler Witkin added, “We knew our friends at CCP would answer the call of Battle of the Bricks, and we look forward to bringing together our amazing communities for this Extra Life fundraiser. It is very inspiring to see our two different worlds join forces for this remarkable cause, with the same creativity and passion that drives us every day. We hope that many of you will join us on July 22nd!”

“We are delighted that CCP Games and Cloud Imperium Games are joining forces to support Children’s Miracle Network Hospitals through Extra Life,” said Adam Schifani, Senior Manager of Community Experience for CMN Hospitals. “We are very grateful to the EVE Online and Star Citizen communities for their generosity and passion!”
