Are my allies just for show?
Solution 1:
Not exactly. They do do something:
- Act as target dummies
- Deal little bits of damage to your enemy
- Look cool
So kind of: they just soak up damage for you (which is helpful in my opinion)
Solution 2:
They passively engage every enemy that shoot at them.
If you aim at high score, you need to kill enemies yourself. If your ally kill enemy, you only get half of points.
You can use "Q" button to give them order to engage enemies.
Later in plot you will have tank under your command, that also will follow your orders same way.
