Power down; conserve batteries. If you still have electricity, (and are safe) recharge. Mobile phones are useful.
- Mobile phone screens are bright. It’s a decent flashlight in a pinch.
- There is likely useful information or applications on your mobile. Phones are essentially small computers now.
- An alarm function can be fantastic for distraction/bait. Place (or toss) it. Move away quietly. Alarm goes off, zombies investigate. Distracted, you can avoid (or ambush) them.
Remember, common objects may be uncommonly useful.
