In Once Human, you can get Rebecca by playing through the LEA Research Lab raid. The best and easiest way is to clear the first level of the raid, where you have to Secure the Polarized Deviants.

The LEA Research Lab Raid entrance is located at the HP Evolution Institute located east of the Blackfell Oil Fields in the Red Sands region. Head there and start the raid either solo or with a team.

Keep progressing until you arrive at the chamber as shown in the above screenshot. Once there, you will find two big Deviants with unique elemental shields around them.

All you have to do to clear the stage is damage the deviants, but only kill them when you are standing within the circle around the corresponding tube.

Once you are done, you will get the Reward Rift and, if lucky, Rebecca; if not, you can press the ESC button and use the 'Exit Dungeon' feature to exit out of the raid.

After that, you can reset your progress from the raid screen and start it again. I got my first Rebecca Deviant on the fourth try.
