This isn’t the hardest trophy, but it can seem a right pain if you try and go ham-fisted on it and just bulldoze your way through.
There are 15 Wenjie’s (That’s what I’ve counted on my play throughs. I’ve seen people suggest there is more though - let me know what you guys have seen yourselves)
3 in the Green Lab
5 in/on the multi-storey blue lab
2 in the red lab (out the back of the tower)
5 in/on the tower
Don’t forget you can use the tower’s depressurisation defence to take out some of the Wenjies inside the tower for you. I deliberately got caught by the top floor sensor then shifted out of the door before the tower locked down.
My route:
3 in the green lab
Through the tower, set off the defences, shift out into blue lab corridor.
Take out the 4 inside the blue lab. Climb to the roof, take out the 5th.
Take out the two on the tower balcony (they don’t get depressurised)
Through the tower again to bottom floor and into the red lab, take out the last two.
