Overall, Gunfight offers a level playing field for all players, providing them with exactly the same tools to determine who can use them most effectively. Matches are short enough to retain players attention with SBMM ensuring that the experience feels somewhat challenging. We can play this mode for hours without getting bored or overly frustrated and were nowhere near close to abandoning it just yet.
