The power of your army is not only in the numbers, what is just as important are the actions available to your units. In Silence of the Siren, every unit can be upgraded to a stronger and more capable version. All you need is the second tier of their recruitment building at your base. Of course, upgrading will increase the unit’s stats and give them a cooler look, but it doesn’t end with that, it always unlocks more options. These can be passive skills that give the unit some advantage which works automatically. Or, what is even more fun: special attacks. There are a lot of variations from powerful area attacks to triggering actions which will change the unit’s behavior. To demonstrate this, let’s have a look at several units from the Fossorian faction as examples.

His pathetic equipment matches the command's trust in his fighting abilities. Normally all he can do is to hit one unit with his hoe in close combat. But if we upgrade him to Ratling Gunner, he is changed into a ranged unit.

Only one of ten adepts will survive the extensive cybernetic augmentation required to operate a Hammerite power armor. Thanks to the armor, the unit hits so hard that it can strike three units standing next to each other. If you upgrade it into a Hammerite Honor Guard, it will get a mighty weapon called the rocket hammer. Now the unit has unlocked a special ability which makes the hits so strong that they will cause a seismic wave hitting all enemies in its way.

In his basic form, he is a close combat cavalry unit, very useful for attacking ranged units. But if you upgrade him, he will turn into Seasoned Commissar. Once in a few turns he can throw his new javelin, causing an explosion that can hit multiple units in a small area.

We plan to introduce more units and their special abilities in the future. How do you like this game mechanic?
