  • cheap install cost
  • very efficient boosting and breaking
  • the all-round best Fracter, all others are measured against it


  • probably the best Fracter out there, even the 2 influence is not that much of a drawback
  • cheap install cost can make it a Power Shutdown target


  • allows the runner early aggression thanks to its cheap cost
  • stays valid throughout the game (unlike Crypsis for example)
  • one of the cheapest Fracters against popular small barriers like Ice Wall and Wraparound
  • hard to say more, just a straightforward and super solid card

Long regarded as the best fracter in the game, Corroder does so by having the best math for breaking ice. At least, across the board in averages that is, in regards to pumpable, non counter breakers. As the game state moves on in horizontal design paths, Corroder becomes less and less as a beautiful end all of fracters. Still quite efficient, others can be more useful, especially as recursion becomes more and more prevalent and the need to get in often is replaced with understanding scoring windows and when to get in.

None the less, this icebreaker was splashed into every conceivable deck for a long while, and still is found as a staple fracter, especially when dealing with the likes of Wraparound. It allows for quick early aggression due to its low cost to install, and its low cost to deal with some of the most popular early game barriers - the most likely cards to be rezed with End the Run subroutines. It is quickly falling to a weakness of mid and late game against large barriers however - Even though it is the most efficient fracter, that does not mean it is cheap. Big barriers like Curtain Wall just cost so much to get through even with cost effective breakers. Barriers are slowly coming back into the frontline now, showing how even cost effective breakers can not be the right ones. However, it remains strong even to this day, and will continue to be worth its influence cost in decks for a long time.
