Firebase Defense offers to experience the classic defense of fortresses with certain updates that add variety and introduce some innovations. It is based on the basic task of self-defense, being behind the provided barricade you need to shoot waves of opponents from various weapons. Here you are allowed to independently build walls, distribute resources and set up firing points. The difficulty is that even the most well-thought-out tactics can have weaknesses, and such a gap will certainly aggravate the situation and cause panic, or even death.

Protection of the firebase begins from the fortress designer, where its shape, thickness, materials, and degree of resistance to damage are selected. A squad with firearms is also given as support to deal damage from a distance. After each influx, the guards need to replenish their ammunition, carry out treatment and update their uniforms. Equipment wears out and ceases to perform its functions; repairing it prolongs life, but over time it becomes extremely fragile and requires complete replacement.

The variety of attackers varies in speed of movement, danger and survivability. For light targets, a short burst of small-caliber barrels is enough; medium ones will fall from heavy fire, but large individuals will stagger only with a powerful, fiery explosion. If the rifle is reloaded in a matter of seconds, then refilling the machine gun belt takes a decent part of the time. For those who like to recklessly shoot with everything they have, a survival mode has been prepared.
