In Invasion Mode in Mortal Kombat 1, players will come across a number of challenges that cut them off from progressing or grabbing treasure. One of the Klues in the Shang Tsung’s Laboratory level is something called Another Test Subject. Behind this Klue is a skin for General Shao, so players will want to figure out how to get to the other side of this level and claim the chest. In order to do this, players will need to do a handful of things, and they might be a little confused about how to complete it.
