    This is one of the harder level to speedrun, even on easy difficulty. Below is a guide for speedrunning this level on legendary courtesy of Nak3dEli and ProAceJoker. Follow this guide an you should have no problem getting this achievement on any difficulty. ProAceJoker did it in about 15:30, You have about 9 minutes for errors, the par time is 25 minutes. Also you can use the save/quit method to set your time back to the point you were at when you originaly hit a checkpoint, but does not work on the last checkpoint of the level.

    This achievement can be obtained with relative ease by playing through the "Hogs, Jets, Tanks, and Mechs" Cross-Game Playlist. "Infinity" is the 4th and final mission in said playlist however the level begins at the vehicle section where you can pilot a Scorpion up to Infinity, completely cutting out the running through the swamps and open area battles that you have to complete in the 1st half of the level. I completed the Scorpion and Mantis sections in about 12 minutes while not focusing on rushing and unlocked the Ouroboros achievement when the level ended. When paused, the menu still stated a par time of 25:00 minutes.

    If you still need to unlock the Sample Plate achievement for completing 3 Cross-Game Playlists, you might want to use the aforementioned playlist as one of the three to make this generally tough par time achievement much easier. And the other levels in the playlist aren't too long either.

    SanjifranGreat solution, just did it today and knocked out par time and score!

    Saved me a lot of hassle, this is a very annoying mission to hit the par time. You have to run through Assault on the Control Room, The Ark and The Storm first, but only AotCR takes much time, and it makes Infinity so much easier.

    keke7302Thank you for the solution, this worked like a charm!

    Finished it in 10 minutes and knocked out the achievement that way, also doing a crossgame playlist on the way.
