Tips and tricks: This achievement in particular will take a LOT of time to unlock, so I recommend you to put the game graphics on the lowest as possible, turn off all the sounds on the game, put some music that you like, and focus on the killzone bar, and you should get it after some rages and PRO Mode ON. Trust me, it took me 8+ hours to get it.

Can also be a little bit easier using Enter (Return) button, tip by M.

Or if you're like EraX you can just simple turn on PRO Mode and get in on 4 tries or less.

Or just turn into a ninja like Fred ♥♥♥♥♥ and get it on 2 tries.

Mass Murdered
Kill a total of 1000 victims in Murder Marathon.

This game mode means daily execution of a puzzle, for which you receive a bonus to your level of bloodlust (see the section below). For every 13 days of the puzzle - a rare weapon. Well, one single achievement.

Lucky Number 13
Go through all the 13th day of the puzzle in "Daily Death"


P.S. The mode of "Daily Death" can be updated by changing the date on the computer, i.e. After passing the test, close the game - put tomorrow's date and come back again. The puzzle should be updated.

At the end of each puzzle in the episode, Jason must commit the murder of the main victim: if you are coping with the task, then increase your bloodlust level. For each such level, starting with the second hero gets the weapon in the collection.
