I remember one time in Fall of Cybertron, me and a friend had been sticking together for an entire match and hadn't died once. Eventually we got pinned down by the entire enemy team outside a door and it looked like we were both going to get killed until the entire rest of our team suddenly arrived out of nowhere and cleaned them out. In that moment I think I had a bromance for the entire rest of the team. Ordinarily I hate everyone on both sides for being incompetent but that was something magical.
