I think that's the consolation medal lol.
Exactly it makes zero sense. I've tried everything to get higher combo medals and nothing works. Like the last boss. First ill team attack him till he's stunned, then I'll use the sword, jump and hit him sending him up into the air, then proceed to draw out 4 unite morphs while he's still in the fucking air, being attacked by everything I've got. He's dead in like 4 seconds, yet here comes the score, oh combo consolation medal. What the fuck?! What the hell counts as a combo in this game?
