8 More Video Game Difficulty Levels For The Criminally Insane

3. Serious Sam - Mental Mode

Serious Sam is indeed very serious when it comes to difficulty modes, as even on the easiest settings you’ll often find yourself overwhelmed by enemies and expending every bit of ammo you have to keep them at bay.

But at least you can see where they are right? Because that’s exactly the liberty that is taken away from you if you play the game on Mental mode. Here enemies will literally vanish before your eyes meaning that a horde of foes will become a see through slaughter force which is especially worrying when dealing with enemies that blow themselves up to do massive damage to Sam.

And don’t even think of trying to outmaneuver them as they now move at nearly one and a half times their speed so will be on your doorstep quicker than you can prepare yourself force. And onces again....they’re INVISIBLE.
