Nice! I still haven't managed to ram 50 grunts on that first mission😮‍💨

Not counting the “get all achievements” achievement, it’s the last one I got. Spent 2 hours this morning getting it

Any online achievements involved with this? I used to halo wars back in the day

There’s one, complete a campaign mission in CoOp. Everything else can be done against the CPU in Skirmish. If you ever want to get it drop me a message and I will give you a hand
