If you want to win more games in Apex, and earn more credits or EXP for your battle pass, hacks can help you power level and get the unlocks you want. Apex cheats give you a massive advantage in the game so you can completely dominate anyone you come across, and survive to the end of every match to claim victory.
If you're playing with teammates it can be very frustrating if your companions get taken out quickly and you're stuck taking on entire teams. With access to cheat features that let you see exactly where other players are, and lock on to them for near-perfect accuracy, you can claim victory in these situations to take the win and carry your team.
Finally, if you're tired of losing matches or playing against cheaters that you have no chance against, you can even the odds and have a lot more fun in the game. Apex is best when you're winning, and you'll be doing a lot of that with access to these cheats!
While there are free cheats available for some multiplayer games, Apex is not one of them. As the game uses Easy Anti-Cheat, and the anti-cheat developers are very quick to ban public cheats, you can't expect to use any free cheats without getting a ban on your account. Why does this happen? Since these hacks can be freely downloaded from sites online, this means that anti-cheat developers can also easily download them and reverse engineer them. Hobbyist coders who create these free hacks typically can't secure them against reverse-engineering and they are detected quite quickly.
