You're the last gun on the rooftop. Aim with the mouse or your finger, hold to fire, and hold the line as the dead pour in from the right — wave after wave, more of them each time, with runners, brutes and the occasional hulking abomination mixed in. Every kill pays out, and that cash is your whole strategy: upgrade your gun from a revolver up to a rifle or machine gun, bolt sentry turrets and backup soldiers to the ground, string barbed wire to slow them, throw up walls they have to chew through, lob a grenade into the thick of it, or patch and fortify the base itself.
It's a tower-defense brain in a shooter's body — you're both the trigger finger and the commander deciding where the money goes. Zombie Defense is an original game made for GameMyself; it runs in any modern browser on desktop or mobile, there's nothing to download, and your best run is saved only on this device. (No gore — the horde goes down in a puff, not a mess.)
