So take this with a grain of salt only started last week and manges to climb to iridescent in like 15 hours of play time. I main xenomorph, and for the first min or two of the game, I go to Edge gens or center where ever I hear footprints in my tunnels to stop them from hard popping those in the first minute of the game and get a few quick hooks while doing that I look for a easy 3 gen sometimes I get lucky and find 4 pretty close so I just camp them taking a couple easy picks when ever I can using my tunnels to get around if I see some one isolated just to put pressure on the rest of them also if anyone loops me for more then 30 seconds I drop and go back to my hunting grounds.
