Y'Know, Moments where your partner would do a combo or move to keep another player in one place so you can preform a super on them?
I had one where I was with a Dante and two spammers and eventually the Kratos had one life left and I used Sly`s "clock" thing to stun him and Dante did the rest.
When my brother and I play, a few that we do are:
Sackboy up throw, PaRappa Lv1
Cole Lv1 during one of PaRappa's combos
And some that happened randomly were:
My brother used his Lv1 with PaRappa right after I did the uppercut with Jak, and killed both enemies. It was awesome.
Another time was in a 2v1, my brother managed to get his Lv 2 with Evil Cole. He used it, and then I just walked up and used my Lv 1 xD
during the beta i was playing witha frien d, i was sweet tooth and my friend was kratos and we were on metropolis. my friend was fighting both enemies on the right side of the stage and was comboing both then lead into an air combo with both of them and i was on the left side of the stage and i used sweet tooths nuke and got a double kill while my friend held them in his air combo.
