Project Neural Cloud - Function Cards

Submit Feedback or Error


Project Neural Cloud's roguelike gameplay revolves around the random generation and allocation of Function Cards during your map playthroughs. For players who couldn't play but want to know what's going on, this page will act as a temporary index of all 72 known Function Cards!

This article will be updated when new cards become available in the Closed Beta Test (CBT), so stay tuned! 

Note that while Function Cards are listed up to level 8 in this page, most cards have no level cap and only a very small number of cards have a limit on the number of times they can be upgraded. The game is also still very early in beta testing, so there may be a lot of downstream balance improvements made to these cards. 

Thanks to Ceia for providing the raw footage! The function card list is translated from NGA.

Function Card Basics

Function Cards are earned during stages and grant various buffs for your team. Their acquisition details were covered in Part 1 - this page will focus on a compilation of their functionality

  • On battle start, function cards that apply to characters will flash over their heads briefly. 
  • During the fight, function card procs will light up the card's icon at the top of the screen. 
    • Some cards may flash over your characters' heads on a proc as well. 

Orange cards (special level function cards) generally have stronger effects than purple cards (high level function cards). Nevertheless, the usefulness of any specific card depends highly on your character roster - adapt to the situation!

Function Card Compilation

Without further ado, let's get to the full card compilation! Once card icons are datamined, they'll be uploaded here. 

All translations are tentative until an official EN release is announced. Numbers are absolutely not final and you should expect:

  • Significant changes to the set of that are available in the final game
  • Numerical re-balancing of any Function Cards that do survive 
  • Card viability to change dramatically based on available unit roster
