When do you get 50% boost?

[masterchiefg]

I just hit 150 points on all runs on gbr thinking I would get 50% but I am still at 49%. Anyone know what points you need to get a 50% boost on GBR?

Almost there. You need 155, so just one more S2 run of each mission.

From what I know, boost rate doesn't effect Boss/Area Boxes, only enemy drops. However, This means... we must hunt down the Jigo Booma and stealz it's Milla! :3
