RAMEach Player starts the game with a a RAM of 0. Each Virus card has a Negative RAM while each Anti-Virus has a Positive RAM.
When a Player uploads a Virus or an Anti-Virus card, their RAM is added (Anti-Virus) or subtracted (Virus) from the Player's RAM.
If a Player's RAM becomes negative, they must format their field by sending enough Virus Cards to their discard pile until their RAM is at 0 or higher.
Data Input CardsData Input cards may be activated by any Player at any time during the game except during the Upload Phase unless it is stated otherwise on the card. Each Data Input card has a RAM cost. To activate a Data Input card, you must pay the RAM cost by returning any number of Anti-Virus cards that have a total RAM equal or more than the cost on the Data Input card.
Battle PhaseDuring the battle phase, the turn player selects which Virus Cards he wants to attack his opponent with by turning them horizontally. The defending player may choose to block them with their Anti-Virus cards.
When an attack hits the defending player, they send a number of cards, equal to the Virus Card's power, from the top of their deck to their Memory. Then they may draw a number of cards equal to or less than the Virus Card's Recode.
When the defending player chooses to block an attack, they select which Anti-Virus Cards to block with and which Virus cards to block against. An Anti-Virus card can block any number of Virus Cards. However you can't block any Virus card with more than one Anti-Virus.
Then you compare the total of the Virus Card's power with the total of the Anti-Virus cards power. If the Virus Card's total power is equal to or greater than the Anti-Virus Card, the Anti-Virus card is destroyed and the attack proceeds to the Opponent. If the Virus Card's total power is less than the Anti-Virus Card, the attack is stopped (The Virus cards are not destroyed). After an Anti-Virus has successfully blocked an attack, it is returned to the defending player's hand.
