I would recommend killing floor 2, as a girl who also doesnt like killing cute things but wants very intense violence its perfect! Theres tons of weapons to choose from, you can play as woman and dress her up in cute outfits, and the game never ends as long as your alive! I have the same problem and this has been my go to game for years! Goodluck!

Sidenote: never use online games or pvp games for this as it will definitely lead to more stress at some point XD
