really good. really really really good. probably my favorite mega man game. i like pretty much all of these stages and bosses which is really rare. upgrades are mostly fun to use and very fun to find. there can be some backtracking involved if you want to get all items or a good ending but i didn't mind because this game's levels, again, are ones i really enjoy. i think most people like this game a little less than X1 but for me it kind of blows it out of the water. worth mentioning that the soundtrack is bangers from start to finish also
