How to unlock the Krypto Come Home achievement in LEGO Batman 3: Beyond Gotham - Definitive Guide
The race itself isn't that difficult but go into it with a flying character, personally I found Batman w/ spacesuit the best.
Another tip: Turn on the mission indicator cheat. I think you can buy that from the start of the of the game you don't need a red brick to unlock it , so buy it from the computer in the Batcave / Watchtower, this makes finding the missions much easier as they can be tough to find on the Hub planets.
Hope this helps.
You need to have unlocked Krypto the Super-Dog first. Refer to “Super Pets” for more information.
Once you have him, select the Man of Steel free play level but do not select Krypto as a character. Start the level then hold down to change your character. Select Krypto and achievement will unlock right away.
This achievement can only be unlocked by playing the Man of Steel level in Free Play. Krypto is unlocked by winning a race against him on Zamaron and purchasing him for 65,000 studs (refer to “Super Pets” in the main guide for more information).
There have been reports that if you select Krypto before starting the level, the achievement won’t unlock. So once you have completed the Man of Steel level in Story mode, replay it in Free Play and select any character other than Krypto. Then, when the level begins, select Krypto as your character and the achievement should unlock straight away.
Krypto's first mission appears after completing all of Green Loontern's missions on Zamaron, which you can't do until after finishing Chapter 15. After completing his mission, you can purchase Krypto for 65,000 studs. Note: It seems that the trophy will not unlock if you start the DLC whilst Kyrpto is your main character, thus you need to switch to a different character then switch back for the trophy to unlock.
