The challenging Callisto Protocol can be easily unlocked with this alternative.

Easily unlock one of Callisto Protocol’s hardest achievements with this neat fix. This alternative easily unlocks the Callisto Protocol’s hardest achievement
The Callisto Protocol is finally here after years of work by Dead Space creator Glenn Schofield. Players assume the role of Jacob Lee, who finds himself a prisoner in Callisto’s Black Iron Prison. What starts as a prison sentence turns into a fight for his life as the Black Iron Prison is overrun by vicious mutant zombies.
Living in jail is not easy and it is even tougher for all the achievement hunters and completionists playing this game. Callisto Protocol has a trophy that requires players to complete the game on the hardest difficulty, and it’s very clear that the hardest difficulty is really, really hard.
However, a clever little workaround has been found to ease the rage-inducing moments. Kinda Funny co-founder and former IGN video host Greg Miller found that players looking to earn “The Protocol is About Life” achievement can easily play through the game on any difficulty and earn the hardest trophy.
All you have to do is defeat the final boss, change the difficulty to “Maximum Security”, run through the rest of the segment, and the tool will unlock.
As always, the choice is up to the players if they want to do so. If not, check out our selection of guides to help ease the trek through Maximum Security, such as how to heal and increase health, how to redeem bonuses early, or a sneak peek at the full list of achievements.
