Halo Spartan Assault: Achievement "Flooded"

And just another little glitch in the game.

For the achievement “Flooded” the requirement is “Complete all co-op missions”.

However, I just unlocked it without ever finishing the 5th (and last) co-op mission.

This is how it happened:

I played (and finished) the first four co-op missions during the course of the last three days, with different co-op partners.
Today I found a random online partner for the fifth mission. We played the mission, but both died, therefor not finishing the last mission, we were not even close to finishing it (we died after the destruction of the very first energy core).

However, my co-op partner decided to play the very first co-op mission directly after that, which we finished successfully.

As soon as we had successfully completed the first mission, “The Company of Strangers” unlocked for me, as well as “Flooded”.

“Flooded”, as I mentioned before, should not have been unlocked at that point, as I never had finished the last co-op mission.

Thank you for the detailed write-up, Vanille Eice. We’ll investigate the “Flooded” achievement.

Just an additional little info:

I just played the co-op with an XBOX Live Friend of mine, He only has played the first co-op mission a few times and then with me just now he finished the second co-op mission. After finishing the second mission, the achievement “Flooded” unlocked for him as well.

My guess: “Flooded” unlocks after you finish five co-op missions and also counts the same mission multiple times. If I am right, that means if you finish the first co-op mission five times, the achievement will unlock.

Instead what it should do is unlock after all five missions available have been finished at least once.
