On Spartan Ops Episode 6 Chapter 3 you can pick up a Gravity Hammer, so it’s rather fun to get a friend and take it in turns batting away Prometheans and see who can launch them the furthest, something else you can do is grab a Banshee (2 on the level) and try pin Prometheans against walls and see if you can get them on top of the Banshee and have them surf on top of it, with a friend you could have a competition to see who can keep one on top longest
