Tips and Tricks

• Strike: Most people know about getting the normal 5 shoes to activate the bowling mini game. However, there is a 6th pair you can shoot through the barrier inside of Liberty Lanes. It is sitting on the toilet and only appears 6 rounds after your last bowling attempt. This shoe can be shot 3 times in one game, allowing you 4 attempts at bowling per match. Additionally, if you load into this with 2-4 players, more zombies appear at once, allowing for more chances at a high score. Ask your friends to not throw any bowling balls for an easier time.
• Terminal: You need to be on Round 51+ for this one, Round 50 will NOT meet the requirements
• Good Enough: Allegedly this is the strategy that was used: https://x.com/HeyImAlaix/status/1853852960003944960. "Spawn in with a weapon and KEEP IT during the whole run. Play normally until round 19 (buy perks, upgrade rarity, pack a punch) When you reach round 19, CRASH your game (idk how to on console but on PC, ALT-F4 should be enough) Load back in your game and play the entire round 19 with that starting weapon and not buy ANYTHING during that round. You should unlock the Dark Ops."
• Stick N' Stones: This has proven to be a little glitchy. You need to reach Round 25 with the listed requirements. However, two things appear to make it bug out: Manglers/Abominations blowing up cars and destroying the Manglers arm cannon. Both will cause an explosion that kills zombies or the Mangler. To avoid the arm cannon, it is advised you go prone before knifing the Manglers. You CAN pick up power-ups, including Nukes, though I would advise against insta-kills due to the explosions causing issues for players.
• Well That Was a Waste: After using the Perkaholic, you will need to be revived in order for the challenge to complete. If playing Solo and you are unable to get back up you will not get the Dark Ops calling card
