Knockout City

This is achievement requires Legendary Gloves, as stated. This can be quite a task which requires playing the game and luck.

In order to unlock Legendary Gloves, here are my three methods, all requiring luck, two cannot be influenced by the player, but can be pushed a little to support that method

Here are the three different ways of obtaining Legendary Gloves

Levelling up- You can gain items from levelling up from the Battlepass, whether you own it or not, at some point (depending what season it is), there could be gloves, the chances of getting legendary gloves are slim, but this is how I obtained them.

The store- Save up your holobucks, and check the store daily to see if there is a set of Legendary Gloves on the store at any point, of course this cannot be influenced by the player, the only thing you can do is save up your holobucks

Contracts- At this point in time, I have not seen a contract for Legendary Gloves. HOWEVER, I have seen contracts for other items in the game, so, in the future there may (or may not) be Legendary Gloves in a contract. If this is the case, complete the contract criteria to obtain the gloves.

Of course, once you have unlocked the gloves, equip them to your current character and win a game in any mode.

(The same method can be applied to all achievements following the formula of "Win a game with legendary... equipped")
