To unlock the hidden unique classes or alternate progenies, you need to fill the relationship meter to four hearts (soulmates). They will then be available to purchase in the quantum synthesizer by using your tech meta-currency.

Hidden Unique Classes

• Gunslinger [Commando + Saboteur]
  
• Juggernaut [Aegis + Enforcer]
  
• Spectre [Empath + Marksman]
  
• Varangian [Valkyrie + Archon]
  
• *Paragon [Win-a-Run] Exception as not hidden at the start, just locked; until you've won a run.

Alternate Progenies
There are many, and most are still unknown. They are basically alternate art variations of their parents, but with slightly different stats and slightly varied skills. Below is a list of known parents that create two progenies.

• Aegis + Paragon
  
• Aegis + Saboteur
  
• Aegis + Spectre
  
• Archon + Empath
  
• Commando + Empath
  
• Commando + Varangian
  
• Enforcer + Marksman
  
• Enforcer + Varangian
  
• Marksman + Juggernaut
  
• Spectre + Paragon
  
• Spectre + Saboteur
  
• Spectre + Varangian
  
• Valkyrie + Gunslinger

Every hero can pair up with at least three other heroes to unlock alternate progenies.

In case you forget which renegades you successfully paired up with each other already; alternate progenies take the colour scheme of the other parent. Example being; the alternate progeny Aegis from [Aegis + Paragon] will take the Paragon's colpur scheme.
