Epic Games has announced at San Diego Comic-Con that Fortnite will be the first game from the Gears of War studio made on the company's Unreal Engine 4. The game will be a PC exclusive.
Unreal Engine 4 is Epic's new graphics engine targeted at next-gen consoles and PCs, although the engine is expected to be scalable to allow games to be ported to mobile platforms and weaker consoles. Read much more about the engine here.
The engine's blueprint modular development tool makes it easy for artists to create new content, Cliff Bleszinski, Epic's lead game creator, explained at today's panel. He also said it makes the game look more clear. Yay for clear, animated skies!
Fortnite is a post-apocalyptic, class-based, multiplayer, strategy-action survival game that runs on a day-night cycle. By day, players will scavenge the landscape, building fortifications, setting traps and doing whatever else it takes to plan for the night. At night, enemy monsters will attack and hopefully your day-planning will have have been good enough to get you through the fight.
Bleszinski said on Twitter that the PC is the game's "primary" platform, leaving the door open for console versions.
