How to play

• Each turn you draw five cards and get three energy.

• Read the foe's intent icon and block on the turns it plans to attack.
• Press End Turn (or Enter) when done; the foe acts, then you draw a fresh hand.

Why you'll play it

• Boss Duel mode — survive one brutal, high-health boss.
• Defensive starting deck with deck growth after every fight.
• Cybercore theme set in a neon megacity grid gone hostile.
• Telegraphed enemy intents, block/energy/strength/poison systems, card-reward choices.
