Besiege has been in Steam Early Access since January 2015, and according to the game's store page, Spiderling Studios plan to continue its development for at least another year before launch. But before that, the developer is releasing a major content update named Multiverse later this year, bringing multiplayer and level editing functionality to the game.
For those unfamiliar, players virtually have free reign to build a variety of machines, ranging from siege weapons to complicated flying contraptions with bombs. Although there are objectives to pursue, the game's sandbox mode is one of its main draws, giving access to plenty of destructible buildings, and NPCs to mow down using creative methods.
The new update's multiplayer component allows eight players to join a server and maximize the damage, either by working together or against each other (well demonstrated in the trailer seen above). Furthermore, thanks to the upcoming level editor, players will be able to create custom game modes, levels, and objectives, which can then be uploaded to Steam Workshop and shared with others. The level editor is also fully multiplayer compatible, meaning players can build levels together in real time.
Besiege Multiverse Update is aimed at a Q3 2017 release, arriving free to all owners of the game. Note that after the update, Besiege's price will increase from $7.99 to $9.99. However, the game is currently discounted by 30% on Steam, dropping it to $5.59 until April 14. If it sounds like something you'd enjoy, this is an excellent opportunity to grab it before the price hike.
