Upgrades are a great help for players to progress through Five Nights at Freddy's: Security Breach. These include those that are for Gregory as they could help him evade detection and attacks from the security bots that are in the Pizzaplex.
In Five Nights at Freddy's: Security Breach, players need to upgrade Freddy Fazbear with the parts that they need to get by defeating several animatronic mascots in the Pizzaplex through boss battles.
