Gnomes are the main enemy unit in this mode. The player's goal in Infinity Time is to survive as many waves as possible by clearing out all enemies until they themselves get vanquished or if their Time Stability is depleted. Once the Gnome Floatie is destroyed, Infinity Time commences and the game is on from that moment until the bitter end.
Once it is full, a Gnome Floatie will appear (though it will not attack) and the player is instructed to destroy it. First, they are instructed to step on a Time Circle to fill up the 'Time Stability' bar on the top of the screen. When the player initially enters Infinity Time, they will appear in a 'antechamber' area, where they partake in a short 'warm-up' activity, before the game begins for real.
In this mode, the player plays as an Infinite Robot ( Junkasaurus for Plants, Mecha Cat for Zombies).
