Firewall Merge: merging defense against waves
In Firewall Merge you build your network defense into a strategy. What is important here is the merging of identical protections: they shoot themselves, and viruses, worms and Trojans go to the firewall line.
How to buy the first protection
- Buy the first protection with the BUY or B / Space button.
- Drag it to the same protection to raise its level.
- Place new defenses so that they hit the waves themselves.
- Don't let enemies past the firewall line.
How many waves does it take for the boss to arrive?
The boss appears every 5 waves. Between bosses you have time to build a stronger defense and reach from Wooden Shield to Omega Core level 100.
How to use Recycle and BOOST
The same calculation of moves is needed in Zombies 4 - Weapon Merge: you decide which identical defenses to connect first. Send weak protections to Recycle for coins. BOOST temporarily overclocks one protection.
