All tutorial achievements

This will unlock the Terminal Velocity Facepalm achievement.
Open the tutorial and go through it until you go to Landing pad, once you get there immediately jump off, repeat this until you get the achievement.

This will unlock the Darwin Award achievement.
Open the tutorial and go through it until you're asked to parasite a marine, swich to parasite (otherwise you won't be able to go into the room you need) then run towards the marine WITHOUT parasiting him, do this until you get the achievement (biting the marine is ok, you can't kill him).

This will unlock the Clogbeard's Treasure achievement.
Open the tutorial and go through it until you're tasked with scanning the alien hive, instead of scanning it scan literaly anywhere else until you get the achievement.

This will unlock the The Last Straw achievement.
This used to be the hardest achievement but it was later made easier.
Follow the tutorial up until you're tasked with building a spur, when that happens watch the gorge and do nothing else until you get the achievement. This is by far the best achievement.

If you think something is unclear, want me to add more images or achievements or something else just ask.
