> Just wondering, how you know you’re the 209th person to get to 152? It would be interesting to see how many people made it there before me by the time I get that rank.
My friend “the Tangybeef” helped me run the math based on HaloTracker’s XP listings. At the time of my achievement, there were 211 SR 152s listed, but there’s a known glitch where if someone changes their username, their old username “ghosts” at whatever XP they were when they changed it. There are two “ghosts” at the SR 152 level, which puts me at 211 - 2 = 209.

I couldn’t do a lot of that Infection. I get too tilted after several games. Only on double XP could I pull that.

Have a night shift job. :-p It also doesn’t hurt liking Firefight.
If you can’t do Infection, Firefight is the way to go. Mostly Heroic Firefight with some Legendary Firefight splashed in when you have some experienced friends with you. Obviously, WZ Gambit: AI Kills, WZ XP Legendary, and WZ Gambit: Medal Count are the best boosts. After that, focus on the WZ XP Rares and WZ Mission Victories; they give 4500 XP each and WZ Mission Victory counts as long as you win one round in Firefight. If you run out of good WZ XP boosts, grab a friend and use Gambit: Assist. They also pay out 4500 XP for the top 2 people for Assists. Just jump into a hog with them and drive them around in the early few rounds. I plan on doing a small Firefight guide in the near future to help get through rounds quicker and successfully, as well as how to get that Grunt Goblin commendation.
Finally, when you play 12v12 Warzone, I recommend WZ XP Jackpot boosts. I’ve noticed that the longer the match tends to go, the higher the Jackpots tend to payout, even if they’re on the lower end.
