Editing VGO's Guide to Warframe (section)

==Missions==
===On The Star Map===
* A rough guide to mission difficulty: you start on Earth, then when ready for the other planets, the difficulty roughly corresponds to orbit number... so, Earth, Mercury, Venus, Mars, Jupiter, Saturn...
* Earth, Venus, and Deimos (Moon of Mars) all have free-roam sections; the difficulty of activities there depend on missions selected in their corresponding city nodes (Cetus, Fortuna and the Necralisk, respectively).
* On your own, you can only visit nodes connected to nodes you've already unlocked. If you're on a team with someone, they can take you to nodes you haven't unlocked. (This is called Taxiing.) If a node normally has a mission that's too hard for you, sometimes it hosts other missions, such as Syndicate missions, or void storms. Doing those missions will also unlock the node.
* (Not sure) Syndicate missions and incursions are always available, even if you wouldn't normally have the node unlocked.

===Quest & Special===

===Disruption Hints===
For Disruption missions, your goal is to kill the Demolyst before they can take out the conduit. There are faint audio and video cues as to where they're coming from. Demolysts have a pulse every 5 seconds that disable Warframe abilities on itself and for 6.5 meters around it. Here are a list of weapons and abilities that can slow it.
* A positive strength Nova's (Slowva) Molecular Prime slows enemies.
* Sevagoth's Gloom is also a good slow.
* Rhino's Stomp halts the Demolyst until its pulse frees it again.
* Loki's Switch Teleport can move the Demolyst back away from the target.
* Magus Lockdown will also freeze the Demolyst.
* A direct hit with the Proboscis Cernos will often stop and slow the Demolyst.

===Mining, Fishing, and Hunting===
The open-world areas have resources scattered throughout which you need special tools to get--tools which are available in their cities for a modest fee. Generally, the "fee" is in reputation rather than actual money, which for Cetus and Fortuna are part of the rewards for bounties.
* Deimos is a little trickier... the bounties don't give reputation directly, but they do give Mother Tokens, which you can trade to Grandmother for reputation.
** Note that Grandmother Tokens are more valuable, so it's worthwhile to trade other tokens for hers before trading for rep.

====Mining====
* In general, the harder a deposit is to get to the greater the probability of a higher value yield--but it's not certain. There is still plenty of low-level stuff mixed in with the higher-level stuff. Still, the easiest way to get the more valuable yields is to go into a cave--if you can find your way out.
* the drill you get from Cetus requires you to trace around the edge of a deposit, with the yield depending on your accuracy; the one you get from Fortuna requires you to find 1-3 drill spots on the deposit and hold down the button just long enough for the trace to stop within the brackets.
* Some of the deposits on Cetus require higher level drills. The drill from Fortuna works with all deposits. It is also upgradable with a silencer. Once the silencer is equipped, it won't alert nearby enemies.
* Sometimes while drilling a node, you'll see a large bracket [    ] and then a much smaller one, [|]. If you hit the smaller one, you're guaranteed to get gems in addition to the regular deposit. That means that on a deposit with 3 nodes, you could get 4 rewards, assuming they all have the option, and you get it every time.
* On the Plains of Eidolon (Earth) and the Orb Vallis (Venus), Red deposits are minerals, and blue ones are gems.
* On Deimos, yellow deposits are minerals.

===Railjack===
You don't need a Railjack to do railjack missions. As long as someone in your squad has one, you're good. Instead ride as a guest in other people's ships until you get tier 3 gear. Then build your gear and railjack, and equip it with the T3 equipment.
