Credits are a unique currency, fueling many special functions and transactions. They can be bought with real currency (an in-game purchase) in the Black Market in amounts of 500, 1200, 2500, 7000, or 15000. Credits are required to purchase Building Threads, instantly compile programs, instantly finish program development and node construction, and change your IP location. They are also used to buy the following items from the Black Market.
Located to the right of the credit bundles are various 9Sec shields, which provide external protection from hacks for set durations. Other players will be unable to connect to a network with an active shield, either by searching the World Map or retracing via the Security Log. However, IPs with an active shield will also be unable to connect to any other networks without first removing the shield. Note that removing a shield cannot be undone, offers no partial refund, and can only be replaced by a subsequent purchase after the cooldown mentioned below.
Activating a 9Sec shield triggers a cooldown during which no additional shields may be activated. These cooldowns begin counting down at the time of activation.
|Black||1 day||100 Credits||4 days|
|Silver||2 days||150 Credits||7 days|
|Gold||7 days||250 Credits||20 days|
To the right of the 9Sec shields are various background and node skins. Skins are unlocked at increasing levels of reputation, which follow the rank increases, except for Ergo Dark. Once unlocked, they can be previewed, even if there are insufficient credits to complete the purchase. Losing reputation does not affect unlocked skins.
