Asterix and the Secret Mission is yet another platform game based on the French comic character. Much like Asterix, every level can be played as Asterix or Obelix, his clinically obese friend, and again the levels are different depending on which character you choose. There are 5 or 6 levels this time, far fewer than in Asterix, and again they are fairly simple, cliche-ridden platform levels - enjoyable, if you like platformers, but hardly ground-breaking.
The plot this time is that you must collect the ingredients needed for a magic potion... one per level. You have to find the ingredient before you can exit a level.
Overall, it varies from easy to tricky, and occasionally veers towards originality, but in the end is Yet Another SMS Platformer.
