9 Final Video Game Bosses That Required Incredible Skill

4. The Lord Of Doors - Death's Door

The inspiration behind this list and a being that is such a tedious individual to fight, Acid Nerve's Death's Door almost turns into Cuphead for its final bout.

Death's Door itself is very moreish to play; easily one of 2021's most recommendable dungeon crawlers. It's very satisfying puzzle and combat-wise, and all four prior bosses are fun to pick apart and defeat.

The Lord of Doors though, crunches all those timing windows down to milliseconds.

Now you need to dodge at the exact right time or get obliterated, the fight comprises multiple stages where the screen itself gets cluttered with obtrusive lasers and summoned enemies now coming at you from both sides.

Even the Lord's health pool is notably bigger than every other boss, meaning you have to stay in that anxiety-riddled state of everything kicking off for a good chunk of time, before he finally goes down.
