Flag submission by PuckJunkie for DOOMPuckJunkie said:For "Specialist" and "IDKFA", I used flags for both collectibles and for leveling: you must collect field drones to unlock the modules for the weapons, and then level those modules up using weapon upgrades awarded in-game for combat, then complete the final level by doing a module-specific task (i.e., kill multiple creatures with detonated rockets 15 times, etc.). An argument could be made for "Cumulative+" as well.
Level select applies, so no collectibles are missable.
Not sure about Runes ("A Gift From Beyond," "The Circle is Complete"), as earning them requires both finding them (collectible?) and succeeding at a challenge. Upgrading them ("Momentum Shift," "IDDQD") requires finding & earning them, then repeating some task a lot to upgrade it. I marked the "earning runes" achievements as collectible, and the "upgrading runes" achievements as "Cumulative+".
Finally, the "mission challenges" achievements give me some pause. Each mission after the first has three challenges, and they may be collectible-oriented, or repeated-action oriented, or exploration-oriented, or whatever. So technically "What Else Ya Got?," which requires completing all challenges, technically will require some collectibles and some actions satisfying the "cumulative+" flag. I put neither on it, feel free to change that.
