The first and only chapter of FortressCraft has no set parameters, quests, or objectives—players are to forge their own personal worlds block-by-block alone or with friends on Xbox Live.

Conversely they may also choose to dig through the ground, hunting for Relics that give bonuses such as the ability to fly, to jump higher, to place TNT charges and blow up blocks, and more.

[3] Adam Sawkins stated that he was looking forward to having FortressCraft playable on the multiple platforms that OnLive provides, specifically the mobile versions.

The original Xbox 360 version of FortressCraft was ported to PC with development beginning February 2021, and re-released on the Steam platform.

[13] Markus Persson, the creator of Minecraft, commented on the game, saying "FortressCraft is an obvious attempt to just take something popular and clone it as closely as possible.

"[14] Adam Sawkins first responded to the criticism with an open letter to Persson, citing Minecraft as an inspiration, but crediting the differences present in FortressCraft.

[16] When asked about Mojang's perception of FortressCraft, the company's business chief Daniel Kaplan stated that they were bored with the video game clones, but that no legal action would be taken against ProjectorGames.

[17] Adam Sawkins responded to Kaplan's comments in an interview with Eurogamer, pointing out key differences between the vox games on the Xbox Live Marketplace and Minecraft.
