Test Subject Complete

Test Subject Complete is a puzzle-platform released on May 7th 2013. The game is the third and final installment of the Test Subject series, wrapping up a series that started in 2011. The game stars Blue as he attempts to escape Doctor Nastidous's base and prevent Doctor Nastidious from achieving world domination. Blue uses the Rex209 in the game, as opposed to the proto-suit.

The sequel was first announced in a May 24th, 2011 blog post, announcing they would make a sequel for Test Subject Green, along with a spin-off title. Although stating that this "sequel" (not the spin-off) would be released in more than two months (and longer than the gap between Test Subject Blue and Test Subject Green), it would be a year and nearly nine months until anything was heard of the sequel again.

Finally, on February 15th 2013, Nitrome revealed a teaser image of the game — and also the game's name: Test Subject Complete. Notably, the sequel to Test Subject Green was greatly talked about in comments on Nitrome's Facebook page and emails — many fans asking Nitrome when then sequel to Test Subject Green will come.

Gameplay
Gameplay of Test Subject Complete varies a lot. From level one to six, the objective is to get the key card and then proceed to the food pill. On level seven, the objective is to shoot the hand of the guard. Levels eight to twenty-five task the player with having to get to a food container.

Levels
Test Subject Complete features thirty levels.

Level 8
This level is the first one out of the test chamber. The player needs to reach the item at the end of the level, in this case it is Wong's Take Out. Follow the most logical way up the platforms and teleporters. Destroy the crawling green enzyme, and if possible, the spinning green one. Get to the checkpoint. Shoot Blue's bullets through the teleporters to make sure they are dead. Then crawl upside down through the teleporter and use the bottom one to get to Wong's Take Out.

Level 10
When the player jumps out of the teacup, fire at the button quickly and pass through the teleporter to Blue's right. Destroy the two guns with three shots. This makes the level much easier than risking to run fast through the level. Try and dodge the green enzyme that throws green enzymes, and shoot at it. Go where it is and go through the teleporter on the platform. Go down and enter the box of floral tissues.

Level 19
This is the first level that includes The Machine. It homes in on the player and when it "locks the target [reticule]", it begins to fire its laser, instantly killing Blue if it hits him. It will continue to fire its laser and move around its reticule, until it stops; it will fire again if the reticule hovers over Blue.

When the laser blasts Blue out of the cup, run left through the teleporter. Once Blue reaches the other side, jump through the other teleporter and fire a bullet at the switch button.

This button turns on or off the blue and orange teleporters. Make sure it turns on the orange teleporter. Go back to the other side and jump through the orange teleporter. Now, things get complicated because Blue needs to be fast. The player needs to jump nimbly across the four platforms and make sure Blue hits the button on the top left, hitting this button once. Make sure Blue does not fall off and go back to the left side.

Go through the blue teleporter to get to the floral tissues.

Recurring
Some enemies from the previous Test Subject games make appearances once again in Test Subject Complete.


 * Walking orange enzymes — The most basic type of orange enzymes; walks at a mild pace and explodes when it hits a wall
 * Dodge orange enzymes — Orange enzymes that attempt to avoid the player's enzyme bullets
 * Shield orange enzymes — Orange enzymes that march back and forth with a shield in front of their face
 * Crawling green enzymes — Green enzymes that crawl across the floor.
 * Bouncing green enzymes — Green enzymes that bounce around the level.

Exclusive
The following enemies only appear in Test Subject Complete:


 * Throwing orange enzymes — These enzymes appear as a mound with two heads, one that is living and the other that is used for defense; the non-living head is thrown at Blue when he comes near
 * Rhino orange enzymes — Big, armored enzymes that move slowly towards Blue. These enzymes have armour plating on their face, armour that comes off the more damage they take
 * Worm orange enzymes — Orange enzymes dropped into the tank by guards. These orange enzymes explode upon contact with any surface, but will release worms that will crawl in one direction.

Recurring

 * Proton cannons — Cannons that shoot orange enzyme bullets horizontally.
 * Detection proton cannons — Proton cannons that aim at the player before firing an orange enzyme bullet.
 * Orange enzyme bullets — Bullets that will kill the player on contact.
 * Mines — Hazards that will kill the player on contact. They can be found on the ground or in the air.
 * Lasers — Hazards that are fired vertically or horizontally and will kill the player on contact.

Exclusive

 * Cooked orange enzymes — Containers that hold liquid orange enzymes. Enzymes in the container will jump or move up and try to hit Blue if it is above them.
 * Enzyme tubes - Shiny silver tubes which drip orange goo droplets that are dangerous on contact. The droplets, upon hitting a platform, will slide along until they fall off.

April 11th 2013
On April 11th, 2013, Nitrome released a trailer of Test Subject Complete.

Reset repeat glitch
If the player presses the "R" button to reset the level, and holds it down, then a glitch will occur. Doctor Nastidious' laboratory will be shown without anything in front of it except for the red cog in the top right corner. Also, the music will play its beginning note over and over again until the player stops pressing the "R" button. This glitch can occur in any level of the game.

Reset level teleporter glitch
If the player is on a level with moving green teleporters that they have moved, and they reset the level, the teleporters will not reset, but instead stay where they were.

Double character glitch
If the player dies on a level, and then hits the reset button before they are fully reconstructed, the player will stay alive but the beginning cut-scene of the level will also play. Blue will jump out of his hiding place, while the original Blue can still be controlled by the player. The original Blue will disappear and the new Blue will become controllable to the player once the cut-scene is over, and the level officially "starts".

Laser sound glitch
If The Machine's laser is being fired while the player resets the level, the sound of his laser going can still be heard. The sound will not go away until the new Machine fires its laser, or if if the player quits the game.

Invisible steps glitch
In the beginning of level 22, if the player goes to the left of the tissue box they spawn at, they will find what seems to be a stack of invisible platforms. If the player presses the jump button (↑) while on the platforms, they will go downwards instead of up. The player can continue to go down even into the cabinet that that they start on, but the platforms end after going two steps down into the cabinet. On the last platform, pressing up will cause Blue to go upside-down onto it. Attempting to move left or right while in the cabinet will result in Blue glitching back and forth, but still staying in the same place. Unfortunately, The Machine is able to shoot the player while they are exploiting this glitch. This glitch is also possible in other levels.

Exit to menu glitch
If the player pauses the game and exits to the menu while a sound is being played (e.g. The Machine's laser sound), that sound will still be heard in the menu. This sound often clashes with the menu music and sounds, making it quite easy to detect when the glitch is occurring.

Invisible platform glitch
In level four, if Blue walks over to the food pill capsule, stands in front of it, and jumps, Blue will stand underneath an invisible platform. Blue can turn around and fire enzyme bullets normally. If Blue jumps into the invisible platform from either side, then it will move into it and fall slowly down to the below platform.

Trivia

 * Many Nitromians thought that the game will be named "Test Subject Red", Rex209, Test Subject Rex(209) or Test Subject Blue 2.
 * The teaser image for the May 21st, 2011, update is the same image used for the menu of Test Subject Arena.
 * The voice for Rex209 is likely some sort of text-to-speech program, and not an actual voice actor, as in the second cutscene in the game, when Rex209 mentions Dr. Nastidious's name, the spoken word "Nastidious" is almost completely inaudible.
