15 Times Players Accidentally Made Video Games Harder

LEFT 4 DEAD – ADAPATIVE DIFFICULTY

Adaptive difficulty has been used in quite a few games over the years, but Left 4 Dead is probably one of the most notable instances. The Left 4 Dead games grow progressively more challenging as you play more, with each new wave throwing hordes of continuously more terrifying monsters at you, but if the game decides that you’re doing too well, it’ll make things even harder, with everything from enemy spawn points to ammo and health pickups getting becoming more challenging as a result.
