Major Deaths

Sometimes during Achievement Hunter Let's Plays, a death occurs that has serious repercussions on the game being played. They can be especially troublesome if the Achievement Hunters are sent a long ways back towards the beginning.

Geoff

 * A couple of suicides alongside the rest of the Hunters in the Wrath of the Machine Raid (mostly because of him losing Geoff Versus Platforming scenarios)
 * Accidentally tagged a cop as he and Ray were leaving the police station, leading to him being killed in an attempted panicked escape. (Ryan felt relieved it wasn't him or Gavin)

Jack

 * Ambushed by a shotgun-wielding terrorist in Rainbow Six Vegas 2 Part 1 with one terrorist left. (In an Achievement Hunter Highlight Reel the ambush is highlighted by James Doakes' "Surprise motherfucker!")
 * Ambushed again in Part 3 with less than 5 terrorists left, only this time it was Jack moving into the situation and not the terrorist.

Ryan

 * Not a death of his character, but in Criminal Masterminds Part 4 a bad parking job near the end of the Prison Break took out his Buzzard's tail rotor, resetting the entire crew back to the very beginning of the heist.

Gavin

 * With one terrorist left at Villa in Rainbow Six Vegas 2 Part 1 Gavin was killed by a case of lag.
 * Suffered multiple deaths during the first wave of Mo'Chievements, mostly by either falling in lava or being ambushed by a Creeper, costing the Hunters a good deal of iron.
 * Gavin suffers a lot of badly-timed deaths in Minecraft.
 * Lost his first gold nugget when he was killed trying to recover it after a previous death

Michael

 * Combined with a capture failure, Michael was unable to complete the first attempt at the final map of Rainbow Six Vegas. (He was successful the second attempt).
 * In Part 1 of 7 Days to Die Xbox Michael died twice, first trying to fend off multiple zombies and then bleeding out just as he reached the back door of a house Geoff (who had bled out himself earlier) was holed up in.

Jeremy

 * In 7 Days to Die Xbox Jeremy made the mistake of walking into a spike trap Jack had set up.
 * While digging for a treasure chest in 7 Days to Die Jeremy was crushed to death in a ceiling collapse.
