Trigger of Silence

Trigger of Silence is a first-person survival defense game set in an invaded world. You play as a super soldier sent to investigate a laboratory, fighting through waves of dragon-like humanoid creatures with melee attacks and guns.

The invasion

In 2040, a laboratory secretly conducts portal experiments. When a glowing humanoid figure emerges from the portal, it takes control of it and brings in a large number of monsters. After the laboratory sends a distress signal, your superiors send you to investigate. You eliminate the creatures you encounter and uncover who brought them through the portal and why.

Weapons and defenses

Weapons can use skill cartridges to unleash powerful abilities that deal heavy damage to groups of monsters. Some weapons can also use cartridges to summon automated turrets.

Waves and vehicles

Large groups of enemies attack at set intervals, and you must clear the hordes to survive. In certain levels, you drive vehicles through groups of monsters and enter their nests to defeat the bosses.
