A handful of enemies from Planet Alpha
You’ll need to sneak past these grumps. If you alert them, hide in cover until their antennae go back to green.
You can’t alert these in the same way as the bots. The downside is that if you cross their beams you’ll die.
Some laser fire is there purely for atmosphere—it’ll just sail past you for the most part, or destroy an object to open up a route.
These are more of a beetle-y looking version of the patrolling bots. Just hide amongst the glowing eggs to lose them.
Often, the bigger foes you encounter are part of a solution to a puzzle. Be warned: They can still definitely kill you, though.
