Deposed

4: War Games Daily Challenge - Earn 3 Regicides in a single match. Complete. 500 XP isn't worth the bullets it took to kill one king.

Sight Seeing

4: Achievement

In Castle DLC matchmaking, completed a match in any mode for each Castle map.

I am very thankful that the Castle DLC is back up for another round. I hope that all 3 additional packs will get to keep rotating in to give us a chance for the achievements.

Spartan Takedown

4: War Games Daily Challenge - Kill 100 Players.
Complete.
Now, this one was worth some effort. Got lots of XP and racked up weapon commendation and even an achievement. An extra 2500 XP not to be snubbed.

Game Over, Man!

4: War Games Daily Challenge - Complete 3 matchmaking War Games matches.
Yeah, complete. No problem. The 600xp was hardly worth note among the rest of the XP I got for the day. What the hell were they thinking?

Castle DLC

4: Wow, just as I put a big bitch-fest on my 4 page about the 3 DLC sets that I missed achievements for - I see that Castle DLC is back on the list and I get one of the 9 achievements for it. Guess I put my foot in it. Thanks for listening.

Creeping 'n Crawling

4: Spartan Ops Weekly Challenge - Kill 70 Crawlers
Too easy, but easy XP.

Also elevated my Knight Slayer to Master and improved Crawler Slayer while I was in there and got a promotion for all the extra XP.

Caboose, THANK YOU.
Going OLD SCHOOL on this one. 6 Cans of Elbow Grease and Headlight Fluid. YES! XD

Thanks to youtube person OvTheDark for showing me where it was sequestered.

Expendable

4: Spartan Ops Episode 8 Complete on Legendary Solo

WOW, hate respawning 70 times in the middle of the elite pack. But I got this done. Now for a few more challenges and to find the RvB Easter Egg.
