Halo 3

One of those pain in the "you know what" achievements... Since the maps just came out (for those of us who pre-ordered Halo Wars) so many people will be going for the Hammer as you'll see once you play. What I did was simply wait for it to drop when the carrier got killed, picked it up and discreetly camped behind the large purple pillars on the outer parts of the map where there's less action going on and when the occassional person would walk by, "BOOM", gone. Repeat this 4 more times and you'll be good.

Note: it doesn't have to be a 5 kill streak with solely the Hammer, as well as it doesn't have to be 5 consecutive kills with the Hammer, you just need to "destroy" 5 people within the course of one match.

Good Luck!!

This is a fairly straight forward Achievement. You need to obtain 5 Kills with the Hammer during any match on the Mythic Map Assembly, other than a Team Swat match since the Hammer will not spawn in that type of match. These 5 kills can come at any time and DO NOT need to be in a row. One here, Two there, etc. Just five kills in the match.

The easiest way to get these kills...After obtaining the hammer...is to wait inside one of the two bases. The big advantage that the two bases provide is that while you can look through the windows to see the rest of the map, people from the outside CANNOT look in. So you can camp at the entrances and hammer unsuspecting passer bys.

This is just one method. To be honest, the 5 hammer kills can be acquired any way you want. Feel free to charge blinding into a hot zone to get a kill. Just remember that you're going to have to then get the hammer back after you respawn. So do it any which way you see fit.

And above all, just have fun with it. Other Mythic Achievements are going to be a lot harder to get than this one, so savior in your moment.

Go to Action Sack and hopefully you'll get Team Fiesta on Assembly, with the many Gravity Hammers laying around, just stand by some man-cannons and you'll eventually get 5 Hammer Kills.

The way I did it was on Team Doubles Ranked playlist. Eventually you'll get a 2 flag game. Just grab the Hammer and defend you base as the opposite team will try to get the flag. Just wait crouched so they can't see you on radar and BAM! Achievement unlocked. It doesn't need to be five straight kills, just five kills during the game.
