Effective Avoidance Strategies

Surviving an encounter with Bacteria relies entirely on your ability to avoid detection and escape pursuit. Here are proven strategies to increase your chances of survival.

Prioritize Stealth

Whenever you suspect Bacteria might be present, stealth should be your primary mode of movement. Avoid making unnecessary noise or sudden movements.

1

Maintain Situational Awareness

Continuously scan your surroundings for any signs of movement or changes in the environment. Listen for any distinctive audio cues that might indicate Bacteria's proximity. Early detection is your best defense.

2

Utilize Environmental Obstacles

Bacteria, like Clumps, has limitations. If you're being chased, look for pools of water or certain staircases that the entity cannot navigate. Jumping into a pool can temporarily halt its pursuit.

3

Strategic Movement

If cornered, try to create distance by using tight corridors or obstacles to break line of sight. Do not attempt to outrun it in open areas unless you have a clear path to a safe zone. Crouching can also help reduce your visibility and noise.

4

Identify Safe Zones

In some levels, specific areas might offer temporary respite. For instance, in the "0.2" sublevel, a Bone Thief can be avoided by not entering a blocked-off area. While not directly for Bacteria, this highlights the importance of recognizing level-specific safe zones.
