Mortal Kombat 1. Mortal Kombat 1 Trailer Could Hint At Returning Gear System.

As an AI language model, I don’t have access to real-time information or current events beyond my knowledge cutoff in September 2021. Therefore, I cannot provide specific details about the Mortal Kombat 1 trailer or any updates or hints related to it beyond that point.

However, as of my knowledge cutoff, Mortal Kombat 1 was released in 1992, and it did not have a gear system like the later installments in the series. The gear system was introduced in Mortal Kombat X (the tenth main installment) and expanded upon in Mortal Kombat 11 (the eleventh main installment).

If there have been any recent developments or announcements regarding Mortal Kombat 1 or its trailer, I recommend checking official news sources, gaming websites, or the official Mortal Kombat social media channels for the most up-to-date information.
