The Infinite

Unlock the Infinite, Act 3's secret area and arguably the ultimate challenge in Mewgenics. This requires completing an elaborate quest chain that spans multiple areas. You need to collect the Receiver Antenna, Transmitter Antenna, and Signal Amplifier, then insert the Signal Amplifier into the Chaos God head at the end of the Rift. This joins the past and future timelines together, opening the Infinite. Reaching this area requires mastery of the game's toughest content and completion of prior secret area quests.
