Boss fights are great ways to test a player's understanding of mechanics in any game, shooters especially. Warframe grants players god-like powers while providing unprecedented levels of mobility for the player to use.

This sandbox should allow for some over-the-top and fantastic boss fights, and it sometimes does. Other times, the bosses in Warframe can be downright frustrating, plagued with invulnerability phases and boring mechanics. Certain bosses need to be killed repeatedly in order to earn new Warframe components or exclusive weapons, which can amplify the fun or dread a boss evokes.

10 Best: General Sargas Ruk

As far as Grineer bosses go, General Sargas Ruk is a solid opponent. He encourages players to swap between various weak points during his simple yet effective fight.

Players fight Ruk in a semi-large arena that gives ample room for bullet jumping and finding cover. He flushes you out with explosive fireballs and flaming pillars he erupts towards the end of the fight. The more damaged he gets, the more flame attacks he deals until the arena is engulfed with flame. It's a fun boss fight that is both a gear check and a skill check.

9 Worst: Lieutenant Lech Kril

Lieutenant Lech Kril is how not to do a weak point-heavy boss. This enemy needs to be shot in the back repeatedly before he is vulnerable to damage.

The issue is the fight is so poorly explained through mechanics that most players don't know to shoot his back to disconnect his tubes. Break all 4 and he becomes enraged and can take damage. Because of this, his second phase is significantly shorter than his first.

8 Best: Teralyst

The Eidolons of Earth are fun bosses players can face once they unlock their Operator and have obtained an Amp. These enemies have interesting attacks, actual mechanics, and reward great loot.

Out of all three Eidolons, the Teralyst is easily the best. It has well-telegraphed attacks that don't harm the eyes like the Gantulyst or Hyrdrolyst. Players must use their Operator to strip its shields and then destroy its limbs using their Warframe. Once a limb pops, it shrieks in pain and summons enemies to kill you. Lures can be found around the map to keep the Teralyst in place and grants more loot on death. It is a fantastic fight that rewards team composition and utilizing mechanics, something Warframe bosses rarely do.

7 Worst: Razorback

If you hate hacking with a passion, never fight the Razorback. This beefed-up Jackal variant deals absurd amounts of damage and can only be damaged after his systems are compromised.

In other words, you have to hack terminals to get small damage windows. This can get incredibly boring when you don't have Ciphers or lack damage. Thankfully, this boss is tied to an event instead of Junction progress, so weaker players can simply skip this encounter. You frankly aren't missing much if you choose to do so.

6 Best: Synthesized Hunhow

One of the best parts of Octavia's questline was the conflict between Cephalon Suda and Hunhow. Towards the end of the quest, players must use the power of music to purge Hunhow from Suda's system.

This fight is one of Warframe's best since it takes full advantage of your character's incredible movement abilities. Players must land on specific parts of the arena while dodging a sweeping laser beam. Later in the fight, they must also slay spawning Sentient enemies. Combined with the story, this fight is a treat to experience.

5 Worst: Mutalist Alad V

Mind control is nothing new in Warframe, but bosses that take over player characters are seldom satisfying. That is exactly what Mutalist Alad V does.

Not only does he take control of a random player but he also has invulnerability phases. You can not damage Alad for most of the fight until he mind controls someone or throws his collar. The worst part of this boss has nothing to do with the fight itself. Rather, players must farm Invasions and certain missions to obtain Mutalist Alad V coordinates, which are then used to craft a one-time mission to fight him.

4 Best: Ambulas

Digital Extremes took fan feedback about boss design when creating Ambulas, and the boss is all the better for it. This MOA has unique mechanics, a great arena, and rewards a powerful Warframe.

Ambulas has weak points on his back that players must destroy with high-powered weapons. When destroyed, players must hack Ambulas so he can be brought back to the Corpus capital ship. Do this enough times and the ship will be overrun and self-destruct, ending the mission. Players earn parts for the Trinity Warframe when fighting Ambulas, giving a strong reward for a fun fight.

3 Worst: Councilor Vay Hek

Invulnerability phases suck for almost any boss fight. Councilor Vay Hek uses them excessively while players are stuck in an uninteresting arena.

After yelling in your ear for five minutes, Vay Hek will begin to attack the player in his arena using weak ranged attacks. He can only be damaged when his helmet opens once every 15 seconds. When he dies, he enters a giant mech that can be instantly killed with well-modded gear. The fight isn't the worst, but the incessant screaming from the character makes this fight much more unbearable.

2 Best: Tyl Regor

Tyl Regor might have invulnerability phases, but they are packed with interesting mechanics that make him a fun boss to fight compared to other bosses.

Stationed at an underground cloning facility, this boss will summon Manic and Manic Bombards at the player, which are terrifying assassin-like Grineer troops. He melees the player but telegraphs his attacks well. When he reaches low health, he releases his clones and floods the arena, significantly reducing the amount of room you have to work with. It is a great way to apply pressure on the player without the fight feeling unfair.

1 Worst: Profit-Taker Orb

Getting stunned to death is not fun. There is no counter-play involved to the Profit-Taker besides having the most min-maxed loadouts in the game.

This enemy summons swarms of Corpus enemies that stunlock the player, preventing them from moving or attacking. Without recovery or stun-immune mods, this fight is too frustrating to even attempt. The fight itself isn't much better, asking players to damage the enemy with a specific damage type and cycling it using their Operator. Rewards for this fight don't match Eidolons and the engagement itself is too frustrating to warrant experiencing.
