Deadpool

Note: This difficulty is unlocked from the start if you are playing on PS4 so you can earn it on your first playthrough instead of doing two.

Ultra-Violence! Difficulty is the hardest one in the game and is unlocked after completing the game once normally. For the most part it's pretty easy especially after your first playthrough (if you did one), you will know the layouts of the maps better and how the enemies act and move. Overall there may be a few tough sections but it isn't that bad, most the boss fights aren't that bad either with some trial and error, nothing should cause too much trouble, except until the final boss.

Even on Easy, the difficulty on the final boss spikes so hard that it can truly be a nightmare on this difficulty, you have to defeat each of the previous bosses again, Sinister and several of his clones. This took me a good few hours to complete and may take you the same. You really need to focus to complete this.

Tips for the last boss:

- Conserve ammo, going empty is the last thing you want, use the pulse rifle!
- Play smart, don't get too ahead of yourself
- Use your special attacks
- Try to use weapons you have fully upgraded!
- Don't use Melee attacks on the final boss as he will more than likely kill you if you try, thus only sparingly use your Melee specials. See the tip below, courtesy of Terminator, for more info:

Melee attacks of any kind are borderline suicide against the final boss (even on Easy) as there's a 95% chance that he will use his Choke and Throw attack on you, which will decimate your health when it hits and leave you open to a cheap death. I found the safest method was to use Flashbang Grenades then shoot him from a distance. All the ammo drops will respawn in time so you don't have to worry about running out of ammo, at least not for very long.
