Hey guys! This is a remake of the original Player Guides, Tips, Apps, & Useful Websites thread created by [DE]Drew.
Helpful DE or player-made threads/websites will be listed here for all of your Warframe needs. If you find a thread that you think should be listed you can send a PM to [DE]Danielle with the link.
GENERAL POSTING TIP:
Before you post on the Forums, please keep the following tips (by IIIDevoidIII) in mind.
The Warframe forums have a multitude of resources to help you on your journey through Warframe:
The Players helping Players subforum contains many help questions and player-made guides, tricks, and tips.
To look for a topic that may have an answer to your question, you can use the search function in the upper-right hand corner of the page as well as the Advanced Search Form.
Detailed information about the game (its lore, mechanics, equipment, and other items) can be found on the fantastic, community-run, Warframe WIKIA.
If you are looking for active assistance in the game, Warframe offers experienced Guides of the Lotus (GOTL). These players are a group of volunteers from the community who spend their time in the low-level Relays, answering questions, and assisting new player with in-game missions, should they be available.
