Fortress TD2

This game is a tactical defense and survival experience set in a zombie-infested world. As the follow-up story, you decide how the tale of special ops ends. The new dialog system lets you interact with characters and uncover the truth about the virus's origin.

The game world has become several times larger, and you now command five battle groups instead of one, each with a unique set of soldiers. The combat system has been fully redesigned with no templates. A universal weapon upgrade system helps you dominate the battlefield, and each soldier has three types of weapons: long range, medium range, and man to man. New battle controls include extra ammo, exploding cartridges, and hand grenades. If there are too many monsters, use the special attack for mass extermination. You can also choose the weapon to mount on your vehicle.

The new game balance system features 12 building types with different functions and 5 lines of research. Take care of supplies and medicines as you face new heights of survival: starvation, thirst, diseases, radiation, and bleeding. It's up to you what you need first: first aid kits, clean water, or battle droids. Don't forget to send scouts to search for supplies.
