Introduction: Sam and Max have been around for a little while and this is their first foray onto the Xbox. If you are familiar with point-and-click adventure games you will be a lot quicker at this game than most, unless of course you slow down to go through every one liner.
Playthrough Episodes 1 - 6: The story mode is completely linear so getting the "Completed Episode X" achievements will come with completing each episode with the exception of Episode 1. In Episode 1, you need to make sure that you say "Attack Me" to finish the level - not "Attack Tapes" - or else the achievement will not unlock. The other achievements can all be missed, if you don't know what you are looking for.
There is an extra achievement for every level except the first one "Culture Shock". In Episode 2, "Situation: Comedy", you need to achieve six different cow identities during the Midtown Cowboys section of the Episode to unlock Improviser. In Episode 3, "The Mob, The Mole, and The Meatball", you need to simply play the Whack-Da-Ratz (right when you walk into the Casino) and not hit any of the wrong rats and you will get Master Whacker. In Episode 4, "Abe Lincoln Must Die", you need to get Max elected president first (as part of the story) and then use the President's calendar to change the date to Easter. After that, go outside and check the golf hole to get Easter Bunny. In Episode 5, "Reality 2.0", you need to basically finish the entire level and get the point where the Internet crashes and you are in a text adventure. Once you are here simply "use" your +2 sword on everything in every area to get Mightier than the Sword. The last missable achievement comes in Episode 6, "Bright Side of the Moon". Unicornicopia requires you to get a total of 10 comments said about the Unicorn you get from Superball. If you show your unicorn to everyone that you talk to in this level, you will get it (show it to Hugh Bliss twice).
Conclusion: Sam and Max will not give you any trouble with achievements as long as you know what you are looking for. Sit back and enjoy Sam and his buddy Max's strange exploits.
