By default, the proximity sensor acts like a grenade. You throw it down, or up, and it lands and spots enemies in a certain radius, visible for all teammates on the minimap. Every time an enemy your sensor spots gets killed, you get points. But what if you could actually ignore its intel-gathering properties and treat it as just another physical object? Here’s Reddit user xFinman doing very much that: using the proximity sensor as a grappling point. By throwing it up in the air and grappling onto it, they manage to quickly travel a decent height. This is basically like grappling onto any higher ledge, except you can perform it anywhere. It’s definitely useful, provided you can land that shot. We’re just thankful this is more on the creative side, and not the glitchy side, of using grappling hooks. Here they are executing it perfectly, and using it to land a rocket launcher shot, too.
