PUBG: Battlegrounds
Terrain seams, bikes, or certain objects sometimes let players slip below the map and attack safely from underneath. PUBG has had many versions of this exploit across maps.
Rapid leaning historically caused awkward hit registration and visibility desync in firefights. The abuser could appear harder to track than normal movement would suggest.
Collisions with terrain or other vehicles could catapult cars and players enormous distances. While sometimes accidental, players also reproduced it for chaotic repositioning.
Small terrain ridges and rocks often let players see and shoot while exposing far less of the model than expected. This head-glitch style abuse is common in PUBG gunfights.
Stockpiling medical items and boosts lets players survive late-zone damage longer than opponents expect, sometimes deciding final placements without clean gunfights.
