15 FPS Gameplay Mechanics That Make No Sense

Killing All Enemies to Progress

So you’re killing enemies en route to an objective, like activating an uplink or disabling a particularly nasty satellite. However, you suddenly find yourself unable to proceed. What to do? Why, kill everything of course! Unlike in older games where doors would magically unlock or keys would drop, we know have cut scenes triggering with the death of all combatants or even – believe it or not – defending against three waves of foes for nearly every mission to proceed.
