Firewall description

Firewall

Firewall is a tower defense game where you defend your network from hackers and viruses. If you enjoy games like Bloons TD or Plants vs Zombies, you’ll recognize the familiar wave-based defense, but Firewall adds a unique cybersecurity theme. Set against a dark background with neon accents and a simple design, the game focuses on building a robust firewall so users can browse the web safely.

Core gameplay centers on placing processes (the towers) to scan incoming files (the enemies). Each file type has a specific process that can scan it best, so you’ll need to choose the right combination and position them along the data path to neutralize threats before they reach the network. Your task is to scan every incoming file and stop malware from slipping through your defenses.

The resource that powers your defense is CPU. You decide how much CPU a single process is allowed to use for scanning. The more CPU you allocate, the more damage a process can deal, but the less remains for other towers. Balance is essential: over-invest in one process can leave gaps elsewhere. If you need more power, you can buy new CPU cores—provided you have enough money to upgrade your firewall’s capacity.

As you progress, you’ll encounter special files such as archives or encrypted data. These files are handled differently and test your strategy, forcing you to adapt and learn which processes are best suited for each situation. They’re a reminder that some threats require careful planning and flexible defense choices.

Economy and progression drive the game: defeat threats to earn currency, invest in additional CPU cores, and expand your firewall. The overall goal is to maintain a safe browsing experience for users while defending against increasingly clever viruses and cyber threats. Success comes from thoughtful planning, experimentation with process pairings, and efficient CPU distribution, all wrapped in a sleek, cyberpunk-inspired aesthetic.

Firewall blends strategic depth with a stylish, minimal presentation. Place your towers, manage computing power, and adapt to new wave threats as you build a firewall capable of protecting the network and keeping users online securely.
