Technologies

To develop the technology tree with your **Library** building is a key element in order to play successful and use all the functions TWD: S has to offer.

The Research System in the game is separated into the following categories:

## **Development Technologies**

Development technologies will offer you a wide range of benefits according to gathering more resources and reduce your waiting times, such as:

* Increased Construction Speed
* Increased Research Speed
* Increased Resource Gathering Speed
* Increased Resource Production

However, there are a couple of key technologies that give you access to new features, we recommend making sure you reach these technologies as soon as possible:

**Water Buckets:** Enables water gathering in the map.

**Meat Collector:** Enables meat gathering in the map.

**Tips:** In times where you are inactive, send some troops to scavenge sites on the map to gain more resources. Improving the “Scavenger” technologies will increase your yield out of it. But be aware: When your troops are outside your town they cannot protect you against other players attacking you. But as a benefit they won’t die or get hurt as well if stronger players raiding you.

## **March Queue Technologies**

March Queue technologies are affecting your respective troop formations and will increase their abilities in the following aspects:

* Gathering speed increase
* Load capacity increase
* Increased attack/defense/health of formation
* Increased Stamina Recovery
* Increased March Speed

Besides these overall benefits, there are also a few **key technologies** that will grant you access to special features or greatly increase your formations power, we recommend researching these technologies as soon as possible:

**Team of Two/Team of Three:** These technologies increase the number of survivors you can assign to a formation. Which will therefore increase the number of fighters a formation can hold and increase the formations overall power.

**Fast Pace:** This technology allows you to use march speed up items. March speed ups can be key in certain situations where a few seconds can make the difference between a loss or a sweet victory.

**Clean Retreat:** This technology allows you to recall your formation by using a “March Recall” item. This is extremely important as you can recall your formation if your target has been heavily reinforced and you can avoid huge losses.

**NOTE:** Additional March Queues (2, 3 and 4) will be unlocked on levels 7, 12 and 18 respectively and their technologies must be researched separately.

**Tips:** In the early stage of the game focus on research “Team of Three” of your March Queue 1. Then once you reached higher levels you can increase your overall March Queues according to your play style and needs.

## **Combat Technologies**

Combat Technologies will improve your overall combat abilities and maintenance of your troops such as:

* Fighters upkeep cost reduction
* Increased Erlenmeyer Flask Drops from Walkers on the map
* Increased Attack/Defense against Walkers.
* Reduced wounded soldiers when fighting Walkers on the map.
* Increased Troop Training Speed and reduction in training cost
* Increased EXP from zombies on the map
* Healing Cost reduction and Increased Healing speed
* Increased Hospital Capacity
* Increased loss to wounded conversion ratio when attacking a town.
* Increase enemy losses when attacking a town.
* Increased troops Attack/Defense/Health
* Extra Houses/Hospitals

Besides all these amazing benefits, there is also a few key technologies that will allow you to promote your troops to your highest level available. There are 3 levels of promotion technologies:

**Fighter/Sharpshooter/Cavalry Promotion 1:** Enables promotion of tiers 1,2 and 3 to the highest level you can train

**Fighter/Sharpshooter/Cavalry Promotion 2:** Enables promotion of tiers 4,5 and 6 to the highest level you can train.

**Fighter/Sharpshooter/Cavalry Promotion 3:** Enables promotion of tiers 7,8 and 9 to the highest level you can train.

It is key that you research these technologies according to your town hall level to make sure you can upgrade your troops to your strongest current troop tier level!

**Tips:** The “Promotion” technology will save your resources as you can just upgrade your existing troops to the highest possible level so you won’t have to train new soldiers every time.
