Halo 3

Halo 3 Achievements

Post Mortem

On Orbital, get 2 Death From the Grave medals during any ranked or social match.  

Get in the habit of throwing grenades. Lots of them! You have to kill someone after your dead. Another way of getting this without using grenades is by using a weapon that travels slowly or over a long distance (such as the rocket launcher of needler). With some luck, you should get this in no time. Plasma grenade stickies just before death are a very easy way to get this, but note that sometimes they won't count as Death from the Grave kills (Mythic Map Pack).

I found that the best way to get this achievement is to play a multi-flag match since it is a lot longer than most game typers. Then, just run around until you find a group of 2 guys and spray them with your assault rifle until you're about to die then chuck a grenade at them. You should get it pretty easily this way, and it's not hard to find a group of two guys on Orbital since it isn't too big. I just found it was easier to get when you were fighting a group of 2 guys than just one guy.

boosting this achievement isn't as straightforward as you might think. I got it today and it took a little while. we tried several methods, including trading stickies, throw a grenade then assassinate before the grenade goes off, rocket from a distance then assassinate, etc. in the end what worked is to stand in an area with a high ceiling, throw a plasma grenade straight up, then have someone assassinate you. when the grenade finally falls to the ground, 2 players from the opposite team jump on top of it. all other methods wouldnt give a death from the grave medal, but this worked every time.

a pretty simple way to get this achievement is on SWAT hopefully the map might be Orbital so just stick two guys before you they kill you, you die fast enough and it can be one at a time not two in one go

Just adding a hint in here, to get orbital as a choice you MUST have 8 players in the game or else you'll only get Citadel, Assembly or Heretic.
Same goes with Longshore and Sandbox, you need 8 players to get it as a choice.

For this achievment your best bet is to have someone on the other team assasinate you immediately after you throw a plasma near two people, and make sure to lob it from a fair distance to give yourself just a bit longer, because these medals only appear if you've been dead for about 3 seconds or so.

Tuesday, May 27, 2014 @ 06:58:54 PM

easy way to get this cheevo if the map loads up with ghosts get someone on the opposing team to meet you in a fairly open spot. have them splatter you but just before they hit you stick them with a plasma grenade. if done right you should get one death from the grave medal. then just rinse and repeat. fairly easy cheevo if you get matched in to it. to get the map for sure with no other maps besides the mythic maps I reccomend team mythic playlist. and legendary cheevos will pop on these maps as well. have fun hunting ;)

Comment #76 by gelfling120742
Tuesday, May 27, 2014 @ 07:03:31 PM

another way is to find the maps rocket launcher and sniper rifle. the person going for the cheevo need the rocket launcher and 2 people standing close together one with the sniper rifle. the one with the sniper rifle lines up a headshot obviously at a distance. count to 3 you both pull your triggers. sniper kill is instant and the rocket should hit at least 1 second after your death. guaranteed death from the grave double kill. both suggestions have been tested by myself and others boosting the cheevo and both work
