Game engine halo's?

I feel noobish asking this, but is there any way to have halo’s show up in the game engine? (Like mesh halo’s) I’m working on a game that look great if i could put some halos in it, but i don’t know how. I tried before but they wouldn’t show up, only in animation and modeling. Is there some way i could texture it or something? Anybody have any ideas?

You can’t use the material halo, but you can come close by rendering it, and then making a transparent plane with the image on. Then you set the object to type “halo” which makes it always face the camera

okay, thanks
