To help test and get feedback on the game, Giovannetti turned to expert players in the Netrunner community. This was also necessary to determine appropriate balance for the cards they added, as balancing the difficulty of the game against the randomness of the roguelike encounters and the card-based play was difficult. By using a large number of playtesters, along with gameplay metric reporting from the game client, they were able to determine what cards had positive designs and which cards to remove. For example, they became aware of cards with too low of a value for the game when they were not picked when offered by players, and found cards that were overpowered if they occurred too frequently within game-winning decks. They had no issue when players discovered card synergies that created powerful combinations, a factor of concern in typical collectible card games, as it was a single-player game and there would be no opponent that would feel overwhelmed by these combos.
