Introduction

Quantum Theory is a third-person shooter video game developed by Team Tachyon and published by Tecmo. The game was released in September 2010 and centers around two characters named Syd and Filena who must fight through a "living tower". Set in an organic sci-fi world, years have passed since a world war left the world in a catastrophic state, leaving only a few survivors. In a new community "Cocoon", life has been threatened by a black material called Erosion, creating a post-apocalyptic environment. Surviving humans recruit a militia to conquer the Erosion and set out to take down the "Living Tower". There is nothing spectacular about the game but if you're looking to burn some money and time and this title is on sale, you might like it for what its worth.


Roadmap

Step 1: Complete Story on Easy, using only the Revenant

Start on Easy mode and complete the game using only the Revenant sidearm. Do NOT use any other weapon. This difficulty is very easy as you can auto-lockon by pressing and the Revenant can kill most common enemies in 3-4 hits apart from headshots. Look for as many Watchers as you can by following the Collectible Guide. You should also attempt to nail down the Achievements What a Pal, 8 Seconds with Style, and Fight Fire with Fire. Completing this step will unlock Trusty Sidearm for completing the game using only the Revenant, as well as give you an idea of what to do during Boss Fights.


Step 2: Complete Specific Chapters on Hard + Boss Fight Time Trials

On Hard mode you no longer have auto-lockon but now you are free to use any weapon you come across, which you should do to unlock Killing Connoisseur. You do not need to complete the whole story on Hard difficulty. On Chapters/Scenes 2, 6, 9, 0-2, 12 and 13, play on Easy up until the last section of each chapter, then quit to the Main Menu. Choose "Continue" in the Main Menu but switch to Hard difficulty and you will resume from the last checkpoint, then you can complete those chapters for the Achievements: Dermal Lesion, Internal Trauma, Phloem, Breach, Subdural Hematoma and Death & Rebirth. Credits to OneChance for this find.

Each of the boss fights on Hard difficulty also have a time trial Achievements associated with it, see the Achievements Professional Exterminator, Gladiator, Warrior, Matador, Nevermore, Entropy and Release for more info.


Step 3: Clean Up

If necessary, you can choose Chapter Select on Easy to clean up on Achievements like What a Pal, 8 Seconds with Style, Fight Fire with Fire, Major League, Cut a Rug, and find any remaining Watchers that you have left. You can also retry the Boss Time Trials on Hard if you missed them on your first attempt.


Step 4: Complete Multiplayer Achievements

I won't kid you, the online is about as dead as a graveyard. There's barely more than 20 people playing it and most aren't really dedicated to boosting the trophies. Speaking of that, you need 1,000,000 points to reach Immortal rank and there is a sort of anti-boosting/penalty system in place that will limit your progress or even send you down a rank or two if you exceed your limit of points achieved in a match. Having that said, if you do manage to find a dedicated boosting party of 6 (you need 8 people for a couple of Achievement), expect to spend anywhere between 30-50 hours depending on your current ranks.

Story Achievements

Pierce the Skin
Clear The Root of the Tower.

See “Dermal Lesion” below.


Dermal Lesion
Clear The Root of the Tower on Hard.

Story Related. You’ll unlock this after clearing Scene 2 on Hard. Play on Easy mode up to the last checkpoint, quit to the Main Menu then choose "Continue" but switch to Hard mode. Complete the chapter to get both related difficulty Achievements.


Through the Viscera
Clear Trachea.

See “Internal Trauma” below.


Internal Trauma
Clear Trachea on Hard.

Story Related. You’ll unlock this after clearing Scene 6 on Hard. Play on Easy mode up to the last checkpoint, quit to the Main Menu then choose "Continue" but switch to Hard mode. Complete the chapter to get both related difficulty Achievements.


8 Seconds with Style
Kill all enemies in Trachea without dying.

This is best done on Easy difficulty because you're riding a Granula which is pretty fast moving and enemies will die easier on Easy. In the first area you come across 3 turret positions. Whenever you see that button alert at the bottom of your screen it means you're approaching one of these positions. The first position has two turrets and a floating red exploding core in between them, shoot the red core to destroy both of them with your MG. The next position has 1 turret and a core beside but you pass it very quickly so I suggest using the Rocket Launcher. The 3rd position has 3 turrets and 2 cores spread in between them, I suggest using the rocket launcher again and aim right in the middle to blast both cores at once.

After that you'll come to a new area and you can immediately lockon to 2 of those flying birds and kill them with you MG. Turn around and more birds will appear, about 5-6 of them so make sure you get them all. You'll be coming upon a platform with 5 soldiers on top next, you can either shoot the red exploding sacs on the ground or use the Rocket Launcher. I use the Launcher for everything since there's enough ammo. You'll circle around the back and come upon a 3rd platform with 3 guys, then a 4th platform with 2 Brutes and 2 soldiers and finally the last platform has 3-4 soldiers, 2 brutes and a turret. Try to get all the soldiers first so that none of them will man the turret.

After killing them all, the next area is free of enemies but you have to shoot Stained Glass Panels as you move on or it'll damage you and might even kill you. You get off at the 3rd area where more enemies are but they should be easy as you can hide behind cover here. Use the Revenant to save your MG ammo.

Finally, you'll proceed to the last fight with the Gargantua boss. Shoot him with everything you got but reserve the MG for when he opens his mouth so that you don't take alot of damage. Once you defeat the boss this Achievement should unlock.


Professional Exterminator
Kill the Gargantua on Hard in 2 minutes 30 seconds or less.

The Gargantua is the spider-like boss at the end of Scene 6. Its weak point is the mouth whenever it opens up to shoot at you, though you still can do somewhat minimal damage when its mouth isn't open. A way to make this fight slightly easier is to play the first parts of the chapter on Easy while conserving ammo, then quit to the title screen when this fight starts. Choose to continue from where you're from and you can change the difficulty to Hard and you'll start with lots of ammo for your MG and Rocket Launcher.


Gladiator
Kill the Chariot during Thorax on Hard in 1 minute 30 seconds or less.

This Chariot is the giant "abnormal Gillskin" that you come across in the second area in Scene 7. The fight can be pretty tough if you don't have the right weapons, therefore I suggest you pickup a Venom MG and the Inferno Rocket Launcher in the first area of the chapter. If you don't see these on the floor, restart the scene as it won't take you more than 5 minutes to reach this mini-boss again. In the game, Filena tells you to shoot his shoulder to stun him then shoot his chest. DON'T waste your ammo and time shooting the shoulder, go directly for the red spot in the chest with your Venom MG. His shots are very damaging and the cover spots here are limited and only temporary because his shots can break them. You can roll under him to buy some time to reload or switch weapons while he turns around.


Xylem
Clear Lumenosynthetic Reactor 2.

See “Phloem” below.


Phloem
Clear Lumenosynthetic Reactor 2 on Hard.

Story Related. You’ll unlock this after clearing Scene 9. An easy way to end the boss fight quickly is to make sure you pickup the Bloodclaw in the first room of the level. When the fight starts, run past Thanatos and up the bridge on the right to the Reactor then whack away with the Bloodclaw equipped. You can end it in less than 30 secs.


Fetus
Clear The Womb.

See “Breach” below.


Breech
Clear The Womb on Hard.

Story Related. You’ll unlock this after clearing Scene 0-2 on Hard. Play on Easy mode up to the last checkpoint, quit to the Main Menu then choose "Continue" but switch to Hard mode. Complete the chapter to get both related difficulty Achievements.


What a Pal
Don't let any teammates who were setting charges go down during the final battle in The Womb.

This is the final scene where your two allies are planting charges on the womb on opposite sides and you will need to circle around keep the enemies off their backs. This is best done on Easy difficulty of course. There’s plenty of ammo around and your MG should suffice, I even did it using Melee attacks only.


Warrior
Defeat Thanatos on Hard in 1 minute 30 seconds or less.

Right at the start of Scene 10 you’ll fight Thanatos in a room filled with exploding Red Spots on the ground. Aim for these spots with the Revenant or any MG whenever he is near one and you’ll beat him easily.
