According to the Twitter account of Epic lead designer Lee Perry, the game will focus on freeform construction, much like Minecraft.
“I see lots of questions asking if Fortnite is freeform construction. It is. It’s not scripted or just boarding up existing structures,” Perry wrote, “and it stands to reason if you can build a world, anything can be destroyed. That’s about all I’m tossing out there for now.” He added that “Minecraft was an inspiration for sure.”
Despite that inspiration, Perry adds that the game will still be different. “Minecraft lets you build anything,” he wrote. “We are focusing on constructing ‘buildings’ specifically.”
For now, Perry added that he still has “no information to give with regards to platform or time frame.”
