The multiplayer shooter, which has been installed 2.5 million times during its prototype phase, will be available from Steam in December.
Featuring upwards of 32 players, users will be able to design their own battlegrounds, all the while competing in team-based deathmatches.
Combining combat and construction, the voxel-based sandbox game will enable users to build elaborate fortresses, small bunkers and underground tunnels, which will dynamically change the course of the battle.
Comparing it to Minecraft and Team Fortress, Jagex CMO David Solari believes that Ace of Spades adds something new to the first-person shooter genre.
"If you're tired of the same old first person shooters, coming out year after year with a fresh lick of paint and a hefty price tag, then Ace of Spades will tick all the boxes for you, offering an all-action multiplayer featuring up to 32-player FPS combat and a fully customisable environment which will continuously develop throughout your battle," he explained.
"Despite keeping this game under the radar during development, it has still proved to be hugely viral with more than two and half a million players entering the prototype phase.
"Ace of Spades is set to take FPS to the next level, adding evolving tactics and strategy to twitch FPS gameplay.
"We have blended the artistic style of voxel-based sandbox games, such as Minecraft, with the class based combat of titles like Team Fortress, and added an extra dimension with real-time evolving battlefields to create a game which we firmly believe will appeal to FPS gamers looking for a bigger challenge."
Ace of Spades publisher Jagex is responsible for massively-multiplayer online role-playing game RuneScape, which reached 200 million registered users earlier this year.
Launched in 2001, RuneScape is recognised by Guinness World Records as the world's largest free MMORPG and the most-updated game.
