Reaction time improvement

I have been playing halo since the original Xbox days. A friend of mine and I recently returned to multiplayer and surprise surprise, nothing has changed for me. I try to do my team some good, but I just keep getting my spartan can handed to me. My problem is that my reaction time is garbage. Playing team snipers, I can’t get any kills because by the time someone appears in my scope, they’ve already killed me.

I need some tips and ideas on how to improve reaction time so I can start doing better again!

Try to anticipate where one would appear / hide as you’re going around a corner. Keep your crosshairs around head height, and perhaps bump up your sensitivities if need be.

It’s one of those things that will develop over time. I’d say to play Swat for awhile since it requires you to have your head on a swivel and it can help you get your reaction time up.

Map awareness. I’d say to just work on your reticle placement.
