Hey there, 
I played on here several years ago and had a blast with a friend both of us 3 boxing.  Think we made it into plane of air when we stopped playing. Might have had some help in plane of fire IIRC.   I'm thinking about trying it again solo if I can figure out the boxing software.  Anyone have any group comp recommendations ? Or have any thoughts on a reasonable goal to shoot for as a solo boxer?  Thanks!
