    As the achievement detail explains, one needs to complete every Research Project available.

    Please note, finishing all of this research requires a sizable amount of these resources:
    Alien Alloys
    Weapon Fragments
    Various alien corpses

    So, it might be smarter not to sell any of those items on the "Gray Market," until all of your research is completed.

    **Edit: Also, if you find yourself well into the game and haven't yet caught a live Sectoid or Thin Man, make sure to use the Council Missions to your advantage -- the "Asset Recovery" Council Missions are almost exclusively populated with Sectoids, and most of the other council missions have Thin Men. Too, you may re-load saves just before Council Missions come up, and you will likely get a different council mission option, so you can pick exactly the kind you need.

    If you're missing the basic Floater, keep an eye out for "Terror!" missions, as you will occasionally see groups of Floaters, as well as groups of Heavy Floaters, during these missions. End Edit**

    Here is a list of ALL 53 Research Projects, as listed exactly in the Research Archives (it looks as though the completed list will be in the same order for each of us, as the list is not in any chronological order of research performed):

    Arc Thrower
    Outsider Shard
    New Fighter Craft
    Hyperwave Communication
    Ethereal Device
    Weapon Fragments
    Alien Materials
    Experimental Warfare
    Psi Armor
    Carapace Armor
    Skeleton Suit
    Titan Armor
    Ghost Armor
    Archangel Armor
    Beam Weapons
    Precision Lasers
    Heavy Lasers
    Plasma Pistol
    Light Plasma Rifle
    Plasma Rifle
    Heavy Plasma
    Plasma Sniper
    Alloy Cannon
    Plasma Cannon
    Fusion Lance (requires obtaining an alien "Fusion Core" from a Battleship)
    Guided Fusion Launcher (requires obtaining an alien "Fusion Core" from a Battleship)
    Alien Nav Computer
    UFO Power Source
    EMP Cannon
    Interrogate Sectoid
    Interrogate Floater
    Interrogate Muton
    Interrogate Sectoid Commander
    Interrogate Berserker
    Interrogate Thin Man
    Interrogate Heavy Floater
    Interrogate Muton Elite
    Interrogate Ethereal
    Sectoid Autopsy
    Sectoid Commander Autopsy
    Floater Autopsy
    Thin Man Autopsy
    Muton Autopsy
    Chryssalid Autopsy
    Cyberdisc Autopsy
    Berserker Autopsy
    Heavy Floater Autopsy
    Muton Elite Autopsy
    Drone Autopsy
    Sectopod Autopsy
    Ethereal Autopsy

    ** Note: Having the "Slingshot" DLC will likely give early access to the "Fusion Lance" and "Guided Fusion Launcher" projects, as one of the missions in this DLC package will have you invading a grounded Battleship quite early in your campaign, where you may recover 2 alien "Fusion Cores" (they are recovered automatically, at the end of the mission, provided you haven't blown them up) that are required for these research projects.

    ThePootermobileI just got a pair of sectoids in a random alien abduction mission in the end game. There were heavy floaters, berzerkers, elite mutons and 2 sectoids. Did anyone ever confirm if regular floaters show up at all once heavy floaters are in the mix? That's one of the only things I'm missing this playthrough.

    RougeRogue1I have seen groups of regular floaters mixed with groups of heavy floaters on Terror! missions.

    GriffinThrale21I am currently playing on normal and am at the end game part. So far I have bumped into every interrogation alien so just keep scanning the world and your bound to happen onto the ones you are missing ( took me an hour to find a regular floater ^^)

    thomaskoratTHERE ARE BATTLESHIPS IN THE GAME? No wonder I didn't get

    Pvt KeoghYep, I'd somehow not gotten a sectoid for interrogation. Turned into a pain trying to get them. They'd pop up in the odd council mission but kept getting killed while I was on overwatch. So I've spent about 2 hours holding off on the final mission waiting for the buggers then low and behold I get a council mission and there is nothing but Sectoids! happy days and achievement popped. Now to complete this first playthrough

    RougeRogue1I put a comment to that effect (the catching of sectoids) a while ago, but, as people are less likely to see the comments, I've added an edit to reflect these most often missed research projects.

    Jock o Strapim missing the fusion lance and launcher, but ive been given the hunter killer cheevo which means ive already shot down a battleship, and ive raided every ship ive shot down. any ideas? they are the only two things i need for this cheevo!
    Posted by Jock o Strap on 16 Jan 13 at 09:41
    RougeRogue1Is it possible that, while raiding the Battleship, you blew up the Fusion Core (an item only recoverable from a Battleship), which might preclude you researching these items? I'm only hypothesizing, as I've not heard of anyone else having this problem before, but this would mean that one not only need shoot down a Battleship, but one must recover said Fusion Core from a Battleship to enable this research -- if this is the case, I'll edit the solution to reflect this.

    Jock o Strapthanks i had an idea it may have been something like that, i guess ill just keep scanning and shooting down ufos until another battleship appears
    Posted by Jock o Strap on 17 Jan 13 at 09:36
    BasanakinI think I saw a battleship once, and my fighter was underpowered. This was in my second playthrough, and since than, I havent seen it again.
    I guess, i better keep scanning ^^
