Mastery Rank 30 Practice Test completed on PS4. This test was available on the PS4 around Oct 14, 2020.
This test is similar to a survival mission. There are 5 stages. In each stage, you need to kill a specific number of enemies, then marked ‘bosses’ will show up.

The life support tower at the end of each stage replenishes 35.
