-NEVER rush a weapon with plat, wait it out
-NEVER buy any resources with plat
-NEVER spend your plat on anything else other than Warframe and Weapon inventory slots and maybe Orokin Catalysts, Orokin Reactors and Forma
-IF you really want to buy weapons or warframes with plat, bundles are almost always a better option
-DO NOT buy platinum unless you've get a 50% or 75% platinum discount award when you log in
-Veterans(like me, Yuri) get those plat discounts more often. If i have a discount active, i could technically buy plat for you or something if needed. I'm a poor bastard most of the time(Croatia village ghetto), but i do have a PayPal account, so stuff can be worked out.
-The aformentioned Catalysts, Reactors and Forma can both be purchased in the market for platinum as well as built in the game - Reactors and Catalysts pop up every once in a while in Alert and Invasion missions
-Forma blueprints can be acquired in Void missions - those are tiered missions(1-4) that give great rewards, rare Prime blueprints and Forma blueprints, as well as some rarer resources(Rank 5 Fusion cores, Orokin Cells,
-Those items increase your mod capacity and reduce mod energy cost, making you drastically more powerful)
-Clear the star chart to unlock access to better missions, this enables access to DARK SECTOR missions which give bonus resource drops, way better credit rewards etc.
-Also clear the star chart to unlock access to potential Invasion and Alert mission locations, so you can get dem Catalyst and Reactor blueprints
-Clearing missions regularly also means that you will eventually stockpile a nice collection of mods and resources needed to get more powerful
-Clearing missions also raises your Mastery Rank. You need Mastery Rank 2 to be able to trade with other players and at Mastery Rank 8 you get access to all available gear and blueprints

-Endgame stuff is: Kubrows(pet dogs), Archwing(space combat), dedicated Void mission farming(you get Prime part blueprints which you can then sell for Plat to other players on Trade chat)
Do not attempt to do these things until you've got at least one full set of gear(Warframe, primary, secondary and melee weapon AND a sentinel) at max level, along with proper mods and installed Catalysts/Reactors

WHAT WARFRAME REALLY IS:

Warframe is pretty much a mix of Diablo, Borderlands and Dynasty Warriors. Think of it that way.
You kill hordes of enemies to get mods for your guns, resources to build weapons, warframes and other utility items, as well as getting rare parts to either build rare stuff or sell it to other players.
Warframe is the type of game where you put your favorite music in the background, get on with your mates and just talk shit while killing thousands(not an exaggaration in certain mission types) of enemies per mission.

This is a game where you can melt enemies into puddles of ooze or freeze them and smash them, or rip them to shreds as an invulnerable rampaging berserker, or stomp the ground so hard that it makes everything around you float and slows down time for everything that survives the initial stomp. Those are just a few examples.

It's an insanely fun power trip.
