About CyberCore Defense Protocol
Defend your vulnerable Core against relentless rogue programs in a vibrant cyber battlefield. Strategically deploy and upgrade high-tech towers to combat ever-evolving enemies.

It leans fully into action, so if that's your thing, it delivers. Whether you want a quick five-minute break or a longer session, it runs smoothly on just about any device.
A couple of things help once you get going: Use the environment: doorways, corners, and high ground all give you an edge. When you die, ask "what killed me?" before respawning. Patterns repeat.
