For best results with proximity mines, start at choke points where hordes naturally funnel through and set your first mine. Position additional mines near gas cans or fuel trucks, since these create bigger explosions when triggered. To maximize damage potential, throw an attractor near your mine setup, which pulls freakers into a tight group before detonation.

Moving to larger targets like the sawmill area, you'll want multiple mine clusters laid out in a path, making sure to stay quiet during placement. Tip: environmental hazards combined with mines work incredibly well especially when dealing with bigger groups so keep an eye out for explosive containers. Once everything's set up, get their attention and guide them through your trapped route, the chain reactions will thin them out fast. Remember to carry extra supplies since you might need backup mines if things don't go as planned

Remember attractors are your best friend here, they bunch up the enemies perfectly for maximum mine effectiveness. Just make sure you're far enough away when everything starts going boom
