Gun Rush is an action-packed upgrade runner where you power up your gun on the go! Start by purchasing and matching parts to create stronger gun components before hitting the track. As you run, make split-second decisions by passing through gates that either boost or weaken your weapon's power. The animated gameplay shows a futuristic runner holding a gun, choosing between green and red power gates labeled with values like "+4" or "-0.6" — every choice matters! Upgrade wisely, blast through enemies at the end, and level up for even more firepower in this fast-paced shooting challenge!
