Side Special: Xeno Dash - It makes a leaping forward dash. If it comes into contact with a wall, it will automatically jump from the wall and will keep wall jumping (as long as there are walls on both sides of it) until an Air Dodge or an Air Attack is used. If it does not come into contact with a wall, it will go into helpless. But if there is wall contact, then it is free to use the move again, but for balance issues, Up Special is disabled until it gets damaged or lands on the ground.
Up Special: Xeno Jump - A super jump that can be angled and charged up. If the Xenomorph hits a wall, it clings to it and can climb up and down the wall for a limited period of time. It can also jump off the wall to avoid going into helpless, but cannot use this move again or Side Special until it gets damaged or lands on the ground.
