Super Destronaut DX released this week and it is one of the easiest completions found on Xbox. You can easily get all 13 achievements in around 20 minutes.
If you need help (You won’t) I have a video of myself getting the 1k gamerscore live on Twitch in around 18 minutes real time. Watch Super Destronaut DX 1,000 Gamerscore from Stallion83 on www.twitch.tv
