Generation Retro begins with a easy cube section. The main antagonist of the level, a red alien, says 'Welcome!', after which there is a transition with blue pads with the level name above. A robot section follows during the drop, which features a custom key being collected and some gravity switches. Near the end of this section, the red alien is seen again, who angrily says 'No!' and then angrily flies into the sky. This is followed by a wave section that flashes between green and red. Halfway through, text reads 'Virus Detected', and the part turns red. The player then turns into a mini-wave after this, before the level switches back to green, indicating that the virus is now gone. After this is a ball section where the aliens serve as platforms. There is a fake in this part where the red alien disguises itself as a normal alien and kills the player if they land on it. There is an arrow pointing down, indicating the fake. Going down angers the red alien who attempts to attack the player, but a blue alien comes to the rescue, saying 'Hey!', stopping the red alien in its tracks. The rest of the ball continues as normal. After this is a UFO section where the red alien attempts to attack the player again, but thankfully they are protected by shields which are shot at by the red alien, thus creating a path for the player to go through.  

After the UFO, an alien that is presumably one of the red aliens minions appears, who evilly laughs at the player with a 'Jajajaja', before declaring that 'You Have Not Win!', and tells them that 'You......DIED!!'. The player screams 'NOO!!' in horror after hearing this information. This begins a boss fight that lasts the rest of the level. The alien immediately shoots a laser in the middle of the screen, which the player must dodge, and then moves up to shoot another one. Thankfully, a weapon appears in the middle of the screen which the player collects. Once collected, the player fires multiple rounds of green ammunition at the alien, draining half of its health. The alien continues its assault, shooting another laser in the middle of the screen. It then fires a column of three projectiles, which can avoided by being at the top or bottom of the screen. The alien then moves up and shoots another column of projectiles. After it does this, the blue alien from earlier comes back and screams 'Nooo!' at the alien, before declaring that 'This Is The End... For You!!'. The red alien can only scream out 'NOOO!!' in horror before it is obliterated by the blue alien's laser. However, it is not over just yet; that was merely the beginning.

The player enters 'Level Final', and the screen flashes as the level turns red. The red alien from earlier has come back for revenge, angrily yelling out 'Aaarrghhh!!', before declaring that 'This is my game!!', and tells the player that 'Its [sic] Time For a Game Over!!'. The alien shoots a laser in the middle of the screen, before causing spikes to appear at the bottom and shooting another laser at the player while moving up. Thankfully, a shield appears and indicates that the player must go up to avoid the spikes and laser. The shield then indicates that the player must move downwards to avoid more obstacles. The red alien angrily yells out 'Aaarrghhh!!' once again, and shoots another laser. The red alien attempts to ram itself into the player. Once the player avoids its attacks, it laughs with a 'Ja ja ja', and declares that it is now 'Game Over!!', before creating an impassable spike wall.  

All hope seems lost for the player, but suddenly, the blue alien comes to the rescue! It yells out 'Nooo!!'and destroys the spike wall with a laser, causing the red alien to angrily yell out 'Aaargghhh!!' once again, who quickly recognizes the blue alien from before. It asks 'You Again!!?', to confirm if this is the same alien from earlier, which the blue alien responds to with an enthusiastic 'Yeah!!'. They then tell the red alien 'And we Will End!!', which causes the red alien to yell 'NOOOO!!' in horror. The both of them shoot a laser towards each other, creating a white flash in between the two lasers. Unfortunately, the red alien's laser overpowers the blue alien's, killing the blue alien. The player yells out 'NOOOOOO!!' in horror as the blue alien dies in front of them, while the red alien cruely laughs at the blue aliens demise with a 'Ja ja ja ja!'. However, the player has had enough of the red alien and takes matters into their own hands. The player angrily yells out 'GAME......OVER!!', before a white flash appears from within them. They shoot a laser at the red alien, finally defeating them and avenging the blue alien. The red alien can only yell out 'NOOOO!!' knowing they have been defeated by the player. The level comes to an end after this, showing an end screen with texts reading 'Score: 9999', 'GG xD!!' and 'Part 2!!?', along with the Lenny face, the creators name, and the object count.

*At 17%, if the player flies off the structure or misses the second green orb, they will pass by a weird circular object with decorations (and an eyeball not present when skipping the orb) with no group IDs attached to it, and is not a coin.

*Generation Retro used to receive heavy amounts of hatred when it was initially added to the Poison Gauntlet due to the unfitting theme and long boss fight. It still gets a vast amount of hate for its difficulty, poor playtesting and decoration according to the community and other reasons.

**ArathhSA, the creator himself, commented on the video, confirming that he made Generation Retro when he was 13.

**This video prompted users McMiner3244 and SpaceMagicGD to create a remake of the level Retro Generation, fixing most of its problems. Another Generation Retro remake, created by the user ZenyXcz, was called 'Retro Legacy'. It also fixed the original level's flaws, alongside improved visuals.

* The levels end screen states that there is 22,935 objects in the level despite the actual object count being 23,084.
