Trojan Planes is an active ability exclusive to the Neurax Worm DLC. It allows the player to hijack planes with hosts and fly them to any selected country. This can be very effective when infecting healthy or closed-off countries during gameplay.
On the Abilities page, purchase "Trojan Planes 1". This will allow you to periodically send a plane filled with infected people to another country, introducing your plague to that country. Trojan Planes 2, and Trojan Planes 3 can improve it when evolved.
- Trojan Roamers 1 and 2, however, make Trojan hosts travel around in said country. Trojan Destroyers 1 and 2, on the other hand, causes Trojan hosts to be aggressive in said country, which also increases infectivity. The achievement Trojan Horse is earned for forming this combo.
- In the Santa's Little Helper scenario, Trojan Planes are referred to as 'Gift Planes'.
