This Seeking Tech guide will show you how to unlock the Thick as Thieves trophy in Astro Bot. To do so, you need to take the following steps:
1. Rescue Nathan Drake from the Lady Venomara level.
2. You then need to rescue Lara Croft from the Hieroglitch Pyramid stage.
3. The last requirement is to get the camera from the Safari Park area at the Crash Site level. The park will unlock when you find 64 puzzle pieces.
4. Once you are ready, return to the Crash Site level.
5. Afterwards, you need to get close to either Nathan or Lara.
6. You should then press Triangle and then punch the character. Press Triangle again and then keep punching your target until you get to the other character.
7. Once the two are close, press the Up D-Pad button to use the camera. You should then press the R2 button to take a picture and unlock this trophy.
