Not many people seem to have noticed, but iValianT (OP and maintainer of the old Index) left Warframe and requested someone take up his mantle... so I did. Post links to your concepts, or just ones you like! Do NOT post full concepts here! Thanks! WARFRAME CONCEPTS
ENEMY, BOSS, AND ENCOUNTER CONCEPTS
The Index has grown large enough that it no longer fits in this single post, and is continued here.
Also, I am going to be going through and resorting the index in a (hopefully) more intuitive fashion. It has gotten big enough, for example, that simple division of the entities into Grineer, Corpus, Infested, and Other probably isn't specific enough. I will be doing this, however, in my local copy of the index and copy-paste it from Word to overwrite this when I'm done. In the meantime, fire away.
Keep up the good ideas, everybody! - Siub
