When playing through Invasion mode in Mortal Kombat 1, you may have noticed strange objectives during some fights. These are Klues, usually garbled and require deciphering. Think of them as bonus objectives, which require a bit more thought. However, because the Klues aren’t straightforward, it can be difficult to know what to do.
There are several regions in Invasion called Mesas, and you’ll encounter one or more Klue in each. Completing the objective tied to a Klue will lead to a hidden chest which provides rewards like Talismans and consumables.
Here are all of the Klues and their solutions. Remember that these only apply for Season of the Specter – the next season could have different Riddle and Klues.
| Klue | Solution | Location |
|---|---|---|
| ESDORYT TEH DWLOR | Rearranges to DESTROY THE WORLD. To complete this, equip Cyrax as a Kameo Fighter and use his Fatality, Annihilation. | Fengjian Village |
| Toasty!!! | Requires using Scorpion’s Toasty!!! Fatalitity to end a match. Once again, equip him as a Kameo Fighter and use his Fatality to complete this objective. | Sun Do Festival |
| AMNISLTA4 | Rearranges to Talisman 4 and requires using a Talisman four times in a single match. Talismans are pretty easy to come by, so make sure to equip a Talisman with at least four charges. Enter the fight and use it that many times. | Sun Do Festival |
| Flipping Out | This objective involves changing your fighter’s stance by pressing L2/LT. You must do it more than 20 times in a single match to complete the objective. | Tarkatan Colony |
| DEDAERHT | Rearranges to Threaded, which means using Ashrah’s second Fatality Threads of Ill Fate to finish a fight. | Tarkatan Colony |
| Another Test Subject | The Mesa itself is a hint, but you need to use Shang Tsung’s second Fatality to win a match. | Shang Tsung’s Laboratory |
| Quackx10 | During a match, duck ten times, which is done by simply pressing down on the left analog stick or D-pad. | Living Forest |
| NOMED RENNI | Rearranges as Inner Demon, which is Sareena’s Fatality. Equip her as a Kameo Fighter and use the Fatality to finish the fight. | Living Forest |
| ERTECA AOSCH | Rearranges as Create Chaos, and it’s perhaps one of the easiest objectives to complete. Simply equip Havik and use one of his Fatalities at the end of the match. | Living Forest |
| KCIRT TAH | Rearranges as Hat Trick and requires using Kung Lao’s Kameo Fatality at the end of the match. Again, this is the Kameo Fighter version, not the playable fighter, so equip him and execute the Fatality to complete this objective | Fire Temple |
| Use the element that brings life | Those who watched the original live-action Mortal Kombat film will recognize this quote, but it doesn’t apply to Sub-Zero. Instead, you must play as Rain and use one of his Fatalities to end the match. | Fire Temple |
