Like I mentioned, I played yesterday without 3x and did really well. Did not die. So, the game doesn't REQUIRE combo. Only the game's host does that by kicking people who don't meet their personal standard or for whatever reason. I'm a little pissed at getting booted so I can't continue my Crystal Clear quest - I'm 208/214 now, btw. My fox tanks nicely, thank you. Way, way better than birds, IMO. They booted me before they saw me play, btw.
