Fortress TD2 is an Android strategy game developed by otgs17. The game is a continuation of the story in which you decide how the special squad's tale ends. The new dialog system allows you to interact with characters, and you'll be able to learn the truth about the virus's origin.

The game world has become much larger, and now you have five battle groups instead of one, each with a unique set of soldiers. The combat system has been completely redesigned, and there are no templates. Each soldier has three types of weapons: long-range, medium-range, and melee. The universal weapon upgrade system will help you dominate the battlefield, while the all-new battle controls offer 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 includes 12 building types with different functions and 5 lines of research. Take care of supplies and medicines as you face new heights of survival, including 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 in this tactical defense and survival game in a zombie world.
