10 Video Game Secrets Everyone Knows Except You

The Metroid series has always been a game of exploration first. Most of the abilities and upgrades you acquire over the course of playing are geared toward progressing through the world more so than combat.

So it's no surprise that the games also have their fair share of secret mechanics. But the self-healing Crystal Flash in Super Metroid is by far the least likely to find without a friend or your trusty copy of Nintendo Power to clue you in.

It costs a not insignificant amount of ammo, can't be used if you have any full energy reserve tanks, and can only be used at less than 50 health. But by entering morph ball mode, selecting power bombs, holding down the fire button and then pressing L, R and down on the d-pad simultaneously, you can get Samus out of a real pinch if you need to.

Needless to say, this is the kind of thing you could only discover through button-mashing and a lot of luck. And while the cost is high, the huge amount of health you recover is literally a lifesaver in an emergency.
