Injustice 2 has a pretty robust gear system helps give your characters new abilities, or more importantly, new looks. Unfortunately, the gear you get in Mother Boxes are completely random, making farming for the equipment you actually want pretty tedious, until now. A quick autokey shortcut for your PS4's Remote Play can make it so that you can basically go through Injustice 2's single-player mode and collect loot on autopilot.
One of the modes for Injustice 2 is an Endless Mode you can access through the single-player mode's Multiverse section. Basically, Endless Mode allows players to fight against an infinite amount of AI challengers, stacking up exp, gear, and Mother Boxes (Injustice 2's version of a Loot Box). You can game the system further by setting your own character to run on an AI loadout which will basically play the game for you in an AI vs. AI tournament.
The only thing stopping you from starting up this Injustice 2 loot racket and leaving to do something else is that you need to press 'continue' after each match, forcing the player into the role of designated button presser. However, an enterprising Reddit user has come up with a pretty ingenious way to promote yourself from button pressing duties through an auto key system.
Basically, players will set up Remote Play on their PS4s and PCs, download and install an AutoHotKey system, and set it so that your laptop will press "enter" repeatedly at set intervals of time, making it so that your Endless Mode can run all by itself. A more elegant solution than buying one of those weighted water birds and setting it by your PS4 controller.
There are some pitfalls however. If the player's character loses, there's no way for the autokey system to reset Endless Mode, so if you step away from your game of Injustice 2 and your AI character loses, the loot farming stops there. Also, there's no word on a comparable system for the Xbox One version of the game yet.
Injustice 2 features an interesting gear system that allows players to customize their characters with unique abilities and stats tied to specific pieces of gear. There's even specific damage modifiers for certain pieces of gear that apply when the player fights specific characters, mixing story further into Injustice 2's gameplay.
While Injustice 2 gives players plenty of opportunities to earn loot–either through daily challenges, or purchasing them with in-game credit–the Endless Mode appears to be the most direct way players can win loot and go off and do other things. Then maybe come back and actually play Injustice 2 again with some of the new stuff they've won.
