'''Every Extend''' is a series of games, originally developed as a DoujinGame by Omega and later fleshed out into a commercial game series by Creator/QEntertainment.

The series plays somewhat like a ShootEmUp: You move around a 2D plane dodging enemies and enemy shots. However, your sole means of offense is ''blowing yourself up.'' When you blow yourself up, enemies caught in the blast will explode similarly, causing a [[ChainReactionDestruction chain of enemy explosions]] if done properly.

Of course, exploding costs you a life, so you get very frequent extra lives ("extends" in Japanese shmup terminology), hence the title "Every ''Extend''".

The series spans three games:
* ''Every Extend'' (PC, 2004) \\
The first game in the series, and the only entry to be a FreewareGame.
* ''Every Extend Extra'' (PSP, 2006) \\
Features stage-based gameplay, with each stage having a distinct visual and audio theme.
* ''E4: Every Extend Extra Extreme'' (Xbox Live Arcade, 2007) \\
Does away with the traditional lives system and is more focused on score. Features an [[EndlessGame endless mode]], a time attack mode, a [[MusicPlayerGame "bring your own music"]] mode, and a completely different mode called "R4: The Revenge".
!! The ''Every Extend'' series contains examples of:
* ActionBomb: ''You''.
* BlackoutBasement: Stage 4 of ''Extreme''. You have to rely on a radar sweep to see enemies, hence the name "Infrared Radar Tactics".
* {{Cap}}: In ''Every Extend'' and ''Extra'', the maximum number of Quickens you can have is 8, made obvious in ''Extra'' by displaying number of Quickens obtained as a eight-segment meter. However, the maximum number of Quickens you can have and still allow Quickens to spawn is ''five''; once you get 6 Quickens, no more will show up, so getting to 8 is a matter of getting 3 Quicken items to be on the screen at once so you can scoop them all up.
* DifficultyByAcceleration:
** As you collect Quicken powerups, the speed and quantity of enemies will increase. This does, however, open up more scoring opportunities, so collecting a full stock of Quickens is vital to high scores.
** In ''Extreme'' stages 1-3, the music speeds up a few times as you collect Quickens, making it harder to get Beat bonuses. Stage 4, however, remains at a constant tempo.
* EndlessGame: ''E4''. The game is easy enough that it's possible to last for ''hours''.
* EveryTenThousandPoints: That's why it's called "Every Extend". This applies only to the first two games. In ''E4'', finite lives only appear in R4 mode.
* LuckBasedMission: While ''E4'' has the multipliers for hitting the explode button on the beat, getting a good score, especially in the timed mode, is still largely dependent on getting the right enemy formations to show up, and you don't have direct control over enemy spawning.
* PinballScoring: ''Extreme''. To illustrate, not only do scores easily go into the billions, but the online leaderboards show ''logarithmic score graphs''.
* RecycledSoundtrack: ''Extreme'' uses the exact same title theme as ''Extra''.
* SequelDifficultyDrop: Survival is completely trivialized in ''Extreme'' compared to its predecessors. In Unlimited mode, if you are fairly on top with picking up Time Extend powerups, it is possible to play for hours without needing superplay-level skill.
* TimedMission: All stages are timed, often with ways to extend the timer.
* TrueFinalBoss: In ''Every Extend'' Heavy mode, you normally fight the KW Motor...unless you fulfill certain requirements[[labelnote:Spoilers]]Capped quickens or either 7 quickens and at least 4 lives with score either above 800k or under 100k[[/labelnote]], causing you to fight another boss instead, AB-A Hedron.
* VerticalScrollingShooter: Subverted in that you don't shoot at all; you have to explode to attack. In other words, it's not a shoot-em-up, it's a "blow-em-up".
