GTA: 10 Best Secret Missions EVERYONE Missed

5. The Final Frontier - GTA V

Remember GTA IV's pigeons? Rockstar literally placed two hundred pigeons all around their rework of Liberty City, then... didn't give us anything for hunting them all down.

In GTA V it seemed they were determined to right past wrongs, and besides mythical entities like Bigfoot now getting dedicated cutscenes, aliens featured far more prominently and all collectibles gave you something cool.

The Final Frontier mission then, combines the latter two, but only appears if you can find all 50 Spaceship Parts.

Sadly you don't get access to any airborne vehicles (that would have to wait until GTA: Online), but talk to Omega with all the components and he'll concoct the "Space Docker" dune buggy, replete with an alien hum to its engine and various soundbites for its horn noises.
