I wanna rocket punch a thargoid
conventional weapons will likely not do much damage. You'll have to get special anti-xeno weapons to be effective against them. I would fully expect the on-foot combat to mimic and mirror the ship combat ...like it does in most other ways already. So fingers cross on anti-xeno missiles for that rocket punch.
How cool would it be if thargoids just pulsed you on the ground and your weapons were disabled as well as your suit thrusters, only minimal life support still on, and you were effectively helpless as the thargoid approached you and just stabbed you thru the chest with an arm spike or back handed you in the head and broke your helmet open so you die like arnold in total recall almost did.
Just total boss level characters that players will try to take out by ship because they need a team of players on-foot to really handle. But taking them out by ship would be no easy feat either because they'd move and jump around too quickly. Also, their skin is able to adapt to their surroundings making them very hard to see from a ship.
Also, thargoids can spit corrosive fluid that will eat thru your suit and cannot be neutralized without returning to a ship or settlement ...leading to your death if you can't reach neither in time.
It would be nice to have an opponent in the game that just rolls over players who think they can just go in solo and rely on their engineered gear to do all the heavy lifting.
