Mortal Kombat: Arcade Kollection is a compilation of the first three games
of the Mortal Kombat series as they were originally released in the arcades:

* Mortal Kombat
* Mortal Kombat II
* Ultimate Mortal Kombat 3

This collection aims to offer faithful emulations of the original games, and
this time, unlike the emulations used in the Midway Arcade Treasures series,
the start button is not used as the pause button anymore, as certain secrets
on the games required the use of the start button. The game includes online
play, local and online leaderboards and achievements/trophies. It also
includes a few screen and display options.
