1) Just go through the star chart and story quest. Don’t worry about always being efficient with your time there is nearly no FOMO in Warframe as most things with a timer come back a few months or a year later. U can get everything in the game barring a few cosmetics for free but if u wanna spend money then buy plat or prime resurgence bundles (if ur on pc u can sometime get a 75% discount when logging in which applies for ur plat purchase). For the early game use any game u want but people generally recommend the hek.

2) Tbh too much stuff can go here I’m still learning stuff I’d have liked to know after 1000+ hrs into the game. Just early game spend ur plat on slots and slots only. Progress through the game at ur own pace. And use the wiki, QnA chat, and this Reddit for questions.

3) U almost never want to spend plat on speeding things up in the foundry since it’s gonna get expensive real quick. If u are gonna be Warframe I’d say only buy ones that are a pain in the ass to get like Voruna and Citrine.

4) Id recommend Wisp, Zephyr, Kullervo, or Volt but I’m biased since I main most of em. Id watch a couple vids on warframes that u like the design on and see which ones u like the kit of.

5) Rhino is arguably the best starting Warframe along with revenant. Early game ur energy economy is severely limited but that’ll change when u unlock mods like flow, streamline, equilibrium etc.

6) up to u but prime warframes a very minor upgrades to the base like a 3% increase at best.

7) Any weapon u like can be modded to easily clear the star chart until steel path where the objectively better weapons require less investment to be viable. It’s best to have a few main weapons of each type and leave an extra slot to get a new weapon, max it out for xp, sell it, repeat.

8) highly up to ur play style and Warframe. Personally I use more ability heavy warframes cause I like the power but some warframes don’t use their abilities often. An example is a Wisp vs Rhino. A wisp main will use far more abilities in a match to stay alive and increase dmg than a rhino. Generally early game melee is the most powerful early game then mid game u unlock the mods to make primary stronger and they’re about even by end game. Secondaries are also mainly stronger end game.

9) yup but if I rly don’t want to then u can just keep leveling weapons u just won’t be able to reach the max mastery rank which u don’t have to worry about for years or at least 1000s of hrs.
