No character progression. No dialogue. No story. No rewards. No randomly generated levels. No builders.
Only several types of units and weapons. Only several indicators for each unit. Only tactics.

Assault and Defense

When you play as the Assault Team, you must destroy the Defensive team in limited steps. When you play as the Defensive team, you must hold position until reinforcements arrive.

Fire and Maneuver

The fire element "fixes" the enemy in position with suppressive fire, while the maneuver element advances to a new position. Attempting to close without supporting fire will result in heavy losses. Trying to fire without close will result in the assault not being able to be completed within the limited time.

Ballistic Advantage and Cover

Different types of weapons have different ranges. The closer the target, the greater the chance of hitting. If the target is behind cover, the chance of hitting decreases.

Suppression fire

If you fire at a unit from multiple positions simultaneously, the unit will be disoriented and suppressed. This means he won't be able to shoot back.

Bomber-drones and FPV kamikaze drones

They changed the course of war and became so widespread that they were used even in small group battles. The bomber-drone hovers over an enemy unit, aims, drops a bomb, and returns to the operator. The kamikaze FPV attacks faster, but it is a one-use drone.
