LOL overkilled, corpse beating... it can't technically happen in DOA. It's only a knockout. I myself just have a problem with those terms, cuz their so inaccurate: it's ground attacking. And I'm okay when opponents ground attack. "overkill!" haha
Or you could play a 2D fighter, VF or Tekken. No overkilling there! Perfect for pussies that hate it lol. J/k, Overkilling is very lame online.
