The Cyberdemon is the first boss in the game. You fight him at the end of Mission 9 (Lazarus Labs). The fight is fairly easy. In the first phase, he mostly fires rockets which you can easily dodge by running in circles around him. When he uses the laser beam, just do a double jump to the side. A great weapon to down him quickly is the Heavy Assault Rifle with the Micro Missiles Mod. The missiles inflict a lot of damage quickly. When his health is depleted, he will respawn again with a full health bar. He will now be throwing some projectiles at you. Do one jump (not a double jump) to dodge them. There is also a checkpoint at the start of the second phase. When the second phase starts, immediately use the BFG to take away a lot of his health. Then, use the Heavy Assault Rifle or Plasma Rifle to kill him while dodging the projectiles.Defeating the Hell Guards
The Hell Guards is the second Boss in the game. You fight them at the end of Mission 11: Necropolis. The fight consists of two phases. In the first phase, you fight only one of the Hell Guards. He has a shield and you can only damage him when the shield is down. Use a weapon that deals a lot of damage with each hit. The Gauss Cannon with Precision Bolt mod is recommended. Try to get headshots while using it. When he jumps at you, there will be some fire on the ground -- so make sure you jump when he does to evade the attack. Basically, all attacks the Hell Guards do can be evaded by double jumping (in both phases of the fight). In the second phase, there are two Hell Guards, but they do not use shields -- so you can kill them very quickly. When the second phase starts, use the BFG on the two enemies. This will take away a large portion of their health. The Heavy Assault Rifle with Micro Missiles mod deals a lot of damage. It also causes the enemies to drop health and ammo. Simply run around them in big circles and shoot rockets at them to quickly kill them.Defeating Spider Mastermind
Spider Mastermind is the final Boss in the game. You fight her at the end of Mission 13: Argent D'Nur. This Boss has a lot of health. Make sure to enter this fight with full ammo for the BFG. There are two more ammo pick-ups in the Boss fight area. Shoot the Boss with the BFG in the brain. This will stun her. Quickly switch to your most powerful weapon and shoot the brain. While she is stunned from the BFG, you have a few seconds to deal huge damage. With a total of 5 BFG hits in the face and some weapon attacks, you can take away over half her health in a minute. The chaingun with the Mobile Turret mod works very well for shooting the Boss while stunned. It deals the most damage. For the rest of the fight, you can use the Gauss Rifle with the Precision Bolt mod. Just make sure you always aim at the brain. Hitting the legs does not inflict much damage. The Boss uses the following attacks and they can be countered in the indicated ways:
Electric Floor AOE attack: It will electrify the entire room. You must climb a pillar to stay safe. It deals a lot of damage if you do not get to safety.
Lasers: Evade by crouching/jumping.
Melee: Only used when the Boss comes close to you. Keep your distance on higher difficulties. On easy this does not matter much.
Plasma Rifle: It will shoot at you. It is easy to evade by walking around the Boss in big circles or double jumping to the side when she shoots at you.
Note: There is no checkpoint during the final Boss fight.
During the "Titan's Realm" mission, you will reach an cavern area with lots of enemies and a yellow booster platform at the back. Walk up the stairs to your right and follow the wall along the second floor to the end. There is a hidden room behind a crack in the wall that you can jump up to reach. Although it looks like it is too small to get through the crack, you can enter the wall to find a skeleton with a party hat on and a "Happy Birthday!" balloon and cake next to him.
