Containment

Containment is a fast territory-capture arcade game where every cut is a commitment.

Click and drag across open space to build a containment barrier. While the barrier grows, it is vulnerable: if a moving anomaly touches it before the cut is complete, your run ends.

Seal off safe territory and capture at least 75% of the field to clear the wave. Endless waves bring more anomalies, faster movement, and visual themes that change every five cleared waves.

Features: simple mouse-drag controls, one-hit run tension, evolving visual themes, fast restarts and local personal bests. Single-player gameplay without a custom account.

Controls: Click to begin. Drag horizontally or vertically across open space. Capture 75% to clear a wave. Avoid collisions with unfinished barriers. Press P or Esc to pause.

Contain the field. Survive the pressure. Beat your best score.
