Hint: Defeating Makron: To defeat Makron easily, just strafe around the pillars
and shoot rockets at him. Be quick, since he can take you down
with one shot from the BFG 10K. When the robot machine gets destroyed,
stand in a corner of a pillar and angle your view so you can hit
him. This will cause him to become confused and walk back and
forth. Use grenades or rockets to destroy him.

Instead of using rockets and dodging the big pillars, use the
underground tunnels to lure him over and kill him. If done correctly,
this can be done without him getting a shot on you. Open both
doors that are on opposite sides of the room by pressing the blue
insignia buttons on the floor. Once you do this, run to whatever
side he is on, then sit and wait until he is in plain view. Light
him up with either the chain gun or the hyperblaster. You can
even use the shotgun, but it may be too slow. If he is reluctant
to show up in front of the door, you can step out quickly in plain
sight, then back up quickly.

Simply hide opposite a pillar, sidestep out, and shoot Makron
with a grenade launcher or rocket launcher. When his robot walker
is destroyed, run to the other side of the arena (other mouth
of the tunnels- either straight or through the tunnels). Stand
at the edge of one of the pillars so you are aiming diagonally
towards Makron. If you position yourself correctly, you will be
in a very safe position and be able to hit Makron with anything
in your arsenal while being safe from everything in his (the BFG
10K may still get you depending on how well you position yourself).
To get into the perfect position, use a machine gun to slowly
find the place where you can fire past the pillars edge but where
Makron always hits the edge.

Hint: Defeating the level 4 Boss: When you are towards the end of the level, you will
have to fight and destroy a very large orange robot. Use the following
tactics to avoid getting any damage. Stay in the hallway that
you go through to fight the Boss. Get your rail gun out and open
the door. You will see the Boss to your left. Aim and take two
shots -- any more, and you will get hit hard. Back up and go straight
down the hall. Wait for about ten seconds, run forward so that
the door opens, and shoot. Retreat back and wait until the door
shuts. Then, run forward as before, let the door open, shoot,
and retreat. Repeat this until the Boss is defeated.
