In 4.2 you’ll first have to fight through traffic then you’ll arrive at the farm. First take all the pictures, then you’ll activate a cutscene where you see the wasps. There are three beehouses you need to protect, for each you need to kill 15 wasps (lock on with , shoot with ). Once you kill 15 wasps at a single house it’ll notify you that you only have the others to protect.
For the achievement do the above but watch for an opaque red arrow. Those are indicators for bees that are being carried away by a wasp, just locate the wasp by turning in the direction of the arrow, activate slow-mo, and save the bee by killing the wasp.
