On the right side of the page, below the game capabilities (Singleplayer, Achievements, etc) is a link to the EULA
Edit: I think this explains a fair few things:
> This EULA was created by eulatemplate.com for Reentry - An Orbital Simulator, with modifications and additions by Wilhelmsen Studios.
To the game dev, if you're reading this: you may want to read the Steam Subscriber Agreement. It may already cover what you want and you may not need an EULA, especially since this may be unenforcable in many parts of the world.
