Legacy Kollection achievements: full roadmap

How the list breaks down

Legacy Kollection has 35 achievements, and they fall into four groups that are worth treating separately because they demand completely different things.

The completion percentages below are the global Steam figures. They are the most useful single signal on this page, because they tell you what the average player found hard rather than what a guide claims is hard.

The easy ones

The top of the list is where the achievements are effectively free, and there is no reason to plan around them.

More than half of all owners have pulled off a Fatality, which makes it the least remarkable achievement in the set. Any part of the list above 30% tends to arrive on its own. The finishing-move types are covered in full on the fatalities page.

The hard ones

The bottom of the list is dominated by two titles, and that is the single most useful fact on this page: the spin-offs, not the famous games, are where a complete run gets held up.

MK Special Forces holds two of the three hardest. That is not because it is especially difficult; it is because it is the least played title in the collection and its completion achievement requires sitting through it. The same is true of Mythologies, which contributes two more to the bottom of the list.

Hidden achievements

Three achievements are hidden on the list. Steam does not show their descriptions until they unlock, which is why they are easy to mistake for missing entries.

Their completion figures are visible even though their descriptions are not, and that is enough to place them: First Konnection sits at the level of the early completions, while the other two are low enough to belong with the later goals.

A sensible order

The list is large but the sequence is not complicated, because the games overlap. Every achievement in the collection is attached to one of the eleven titles, so finishing a title tends to hand over several achievements at once.

1. Play the arcade trilogy first. Mortal Kombat, Mortal Kombat II, Mortal Kombat 3 and Ultimate Mortal Kombat 3 carry the largest share of the list between them, including most of the finishing-move achievements and six of the ten secret fights. You will also pick up the easy completions while doing it.
2. Take the home ports as a second pass. The SNES, Genesis and 32X completions are separate achievements, and the games are similar enough that the skills carry over.
3. Do the secret fights deliberately. These need specific conditions rather than time, so they are best done in a session of their own. The hidden characters page names the version for each.
4. Leave Mythologies and Special Forces for last. They are the two most time-consuming titles and hold the hardest entries. There is no advantage to starting them early.
5. Finish with Trilogy. The two boss-related achievements sit here, including the run that requires beating the game with both Scorpion and Sub-Zero.

If you would rather watch the documentary and profiles than grind a ladder, the collection includes them, and the contents page describes what is in the box. The AI and bosses page covers the difficulty settings that make the harder runs more manageable.
