Zombie Attack: Defense

GameMonetize

Zombie Attack Defense hands you a full keyboard arsenal and then makes you ration it: A and D to walk, W or space to jump, left mouse to shoot, right mouse for bombs, and Z for the nuke that you get once per run and will waste at least once learning to save. Waves come from both sides, so position is real defense, standing in the middle of the lane splits your attention exactly as badly as it sounds. Bombs have splash radius you can feel out in the first wave, and the economy between waves is tight enough that buying ammo versus saving for a better gun is a genuine choice rather than a no-brainer. The difficulty ramps on a wave-10 boss that punishes hoarders. Free online, no download.
