What could possibly be better than gnome trying to murder each other? Gnomes with jetpacks trying to murder each other. Pick from 1 of 4 weapons and fight to reach 15 kills in order to win each match of Gnomez.
WASD moves your gnome. Left click to fire. Space uses your jet pack. Hold to hover. Though you must reach 15 kills to win, dying takes a kill away from you.
Learn the map. Knowing the location of all the health picks-up will give you quite an edge over gnomes. Also, if someone is nearing 15 kills, focus on killing them to prevent them from winning.
