8 Terrifying Monsters Hiding In Open World Video Games

6. Hydra - Dark Souls

FromSoftware have quickly become the masters of hiding the best and worst things imaginable around the corner. From placing ambushing enemies in shadows to tucking a game-winning item away in a hidden treasure chest, you're incentivised and should remain wary of, every single step taken.

Whilst we've all got our personal picks for which enemy made a horrifying impression - mine being those upturned bone centipede things in Dark Souls 3 - Dark Souls 1's Hydras take the cake for something only getting worse as you get closer.

With two examples - both equally imposing as hell - your first is often seen through the gaps in the trees while wandering Darkroot Basin. That far-off creature actually being a multi-necked serpent firing those energy blasts is one hell of a realisation, though things get worse if wander farther from the beaten path and end up down in Ash Lake.

This more formidable foe has splash damage attacks in literal waves, wiping you out with any one of its heads if you're standing in the wrong place. Combined, the Hydras are both badges of honour only a portion of the Souls fanbase will seek out and conquer.
