I remember when achievements were in Java Edition before being replaced by Advancements. in addition to that Splash Text (Which is a call out for HL3 from Notch) the achievements "On A Rail" (travel 500 blocks in Minecart) and "The Lie" (craft a Cake) are obvious Half-Life and Portal references, but now they are only on Bedrock :(
