"Centurion"

Centurions are a special clan squad and function rather differently than regular units. Unlike normal units, they are not consumed when used in battle. Instead, they have a finite amount of energy (5, to start with), which decreases every time it is used. Once it reaches 0, you cannot use the unit again until it recharges. The simplest way is to wait -- it will naturally recharge at the rate of 1 per hour. However, you can also accelerate this at the Engineer Academy by paying 10 fuel cells or 50 gold.

Centurions have their own special clan squad slot in your lineup and can be used in all missions in the game except for expeditions. They are also deployed separately -- rather than being part of the normal deployment queue, they have their own deployment area at the top-left of the screen, so you can deploy them at any time (assuming you have a sufficient number of deployment points).

Because they are clan units, Centurions are tied to your clan. As soon as your clan builds an Engineer Academy, everyone in the clan can use a Centurion. If you leave the clan, you lose the Centurion as well. The upgrade level of the Centurion also depends on the clan, not the player.

Unit training
The following table lists the upgrades available to the Centurion. In addition to the regular costs, fuel filters and piston kits are also required for upgrades; these can be obtained from the Operation Basilisk clan expedition, as well as from end-of-season rewards. In addition to the regular upgrades, there are also some skills that can be upgraded, which are listed in the table below. Equipment for Centurions is not yet implemented.

1The time listed is only for the health upgrades; other upgrades always take 1h regardless of level.

Unit research
This table summarizes all of the research that can benefit Centurions. For full details, see the specific research pages.

Unit skills
The skills available for the Centurion are as follows. All research points required are mechanics. Note: The description for upgrades often does not match the actual effect of the upgrade. The values shown in the table below are the actual benefits of the upgrade.

At level 7, the active skill of the Centurion, "Rapid fire", is unlocked. This skill activates every 30 seconds, and reduces the reloading time of all units within radius 1 by 0.005 seconds for 5 seconds.
