What is Space Engineers?

What players say

89% of 134,470 reviews are positive · 75% of 202 in the last 30 days

Players praise the freedom to design functional ships, bases, and elaborate engineering projects, along with extensive mod support. The most common complaint is that unowned DLC blocks remain visible throughout the interface, making the base game feel like an advertisement; players also report poor optimization, persistent bugs, and weak tutorials.
