* CrowningMusicOfAwesome: Pretty much every game in the series, especially ''Turrican II''. In fact, that game had a live orchestral performance of ''Turrican II's'' soundtrack in Leipzig, Germany.
* EvenBetterSequel: Turrican 2 has bigger worlds, better weapons, improved graphics and possibly the best music.
* GameBreaker: In ''Turrican 3'', you can find a secret powerup in the beginning of the second world. This turns your suit gold and you powerups will no longer downgrade if you lose a life. However, getting a GameOver and continuing will lose the suit. This is absent in the original ''Mega Turrican'' version.
** Wheel mode in ''Turrican II'' has no limitations and makes you immune to nearly all forms of damage, making it trivially easy to pass through screen-filling lasers unscathed.
* GoddamnedBats: Robot bee hives, especially if you don't have a levelled wide-angle weapon. Also the, well, bats in World 4 of the original, which are hard to hit and constantly spawn clones which spawn more clones.
* IAmNotShazam: Turrican is the name of the PoweredArmor worn by the hero, who may or may not be a different person each game.
** The intro of the third game names him "Bren."
** LegacyCharacter, possibly.
* PortingDisaster: The first two ''Turrican'' games suffered from this. The Mega Drive/Genesis port was the most intact, but had clunky controls; The Turbografx-16 had the same clunky controls and also was missing all of world 3 and had a limited soundtrack; and the Game Boy also has a world missing as well as sluggish controls. ''Turrican II'' was worse. It was released as Universal Solider [[{{The Problem With Licensed Games}} as a movie tie-in for the Mega Drive/Genesis and Game Boy]]. Ouch.
** Actually, averted with Turrican 2. "Universal Soldier" plays exactly the same as the original game, just with new graphics and a different story.
* {{Sequelitis}}: The first two games created by Manfred Trenz are generally considered superior to the sequels that followed without his involvement.
* ThatOneLevel: World 4 in ''Turrican'' is a massive three part maze with creepy ambient sound instead of the CrowningMusicOfAwesome featured everywhere else. Power-ups are much harder to find than normal, and even if you know where to go, dozens of pixel-perfect (and sometimes entirely illogical) jumps are required to reach the exit. All of the [[WombLevel womb levels]] in the sequels have similar length and difficulty, but the first one took the cake.
* TheyChangedItNowItSucks: See PortingDisaster above. Other examples include ''Mega Turrican/Turrican 3'' and ''Super Turrican 2'' having more linear levels, and both ''Super Turrican'' (SNES game) and ''Super Turrican 2'' had your lightning beam changed from an attack to [[LightningCanDoAnything freezing enemies]].
