It started in Gears of War 1 and it carries on in the sequel.
No, not the fight against the Locust. No, not the continuing Carmine bloodline. Rather, the argument over which is better - Execution or Warzone.
Both game modes are about taking eliminating the other team by killing them. The difference is that in Warzone, you can kill downed players by shooting at them while Execution requires... well, an execution. Hence the name.
While they appear similar, the subtle differences are huge, as they make Warzone a slower-paced, deadlier game while Execution becomes faster and revolves around power weapons for the all-important instant kill. But which mode is better? And which one is truly noob friendly?
