Ammo Scarcity, Not Zombie Count, Is What Makes These Games Tense

Plenty of games hand you unlimited ammo and call it action. Zombie survival titles do the opposite on purpose, and that scarcity is exactly why a slow shuffling horde feels scarier than a fast, well-armed enemy.

Every decision costs something. Spending three bullets on one zombie means three fewer for the next room. That math runs in the back of your head the entire session, which regular shooters rarely bother with.

It rewards avoidance over aggression. Sneaking past a horde to save supplies often beats fighting through it, which flips the usual instinct to just shoot everything in sight.

Silence becomes a resource too. Loud weapons draw more of the horde, so the quietest option isn't always the weakest one - it's often the smartest.

None of this needs complicated crafting systems to work - even a simple browser game gets real tension out of just making bullets count.
