to call in support, you use a beacon that you configure by pressing UDLR. if your teammate does this, you can see their character using their finger to type it in
the beacon is a proper physics object. it bounces, rolls, and drops. think about where you're throwing it!
the physics, needless to say, hates you
both your character and every one of your enemies are modelled down to the level of individual limbs, with movement actuated by moving said limbs. no limb = less movement
