10 Awesome Video Game Features We Can't Believe Got Cancelled

10. The Mantis Mask Lets You Read People's Minds - Metal Gear Solid 2: Sons Of Liberty

Twisted genius Hideo Kojima is one of the most left-field creatives working in the games industry, so it's little surprise that he's been forced to leave countless ideas on the cutting room floor over the years.

But there's one single mechanic above all others whose deletion is painfully lamentable. While designing Metal Gear Solid 2: Sons of Liberty, Kojima originally planned to include a "Mantis Mask," based on the prior game's iconic boss Psycho Mantis.

The mask would allow users to read the minds of anyone in the vicinity, and per Kojima's typically inscrutable eye for detail, it goes without saying he would've allowed players to have a ton of fun with the mask on both NPCs and bosses alike.

The mask could reportedly be unlocked for a second playthrough and allow players to immediately see through Solid Snake's unconvincing alias Iroquois Pliskin.

It's genuinely surprising that Kojima never brought the Mantis Mask back for future MGS games, and while it could certainly slot easily enough into any future titles - especially if the rumours of a PS5 Metal Gear Solid remake are true - Kojima's acrimonious split from publisher Konami sadly makes that prospect rather unlikely.
