For regular Star Chart you can make every weapon work without too much investment, so go for whatever you think you will enjoy!

Whenever you unlock the "Steel Path" you will need to pick and choose a bit more careful what you invest too, especially when you have limited ressources. But that's a topic for later!

Still, you can make literally every weapon and Warframe work in this game, some just need a little bit more help than others.

That… doesnt really help

Well, you seem excited about the MR9 test. If you're trying to get through MR, you need to build and rank up everything. So, build them, use them, decide whether or not you like them.

Depending on how far into the star chart you are: twin grakatas are fun, but need heavy modding for upper tier does.

If you are waiting for things to come back around in resurgence: might as well keep building and ranking up what you can while you wait.

Ok, so izz G R A K A T A Time

Did somebody mention Grakata

Y u p

Oh dude you have no idea. I've been using Grakatas for the last 8 years. It's objectively a sub-par gun. There are far better options, but none come as close to the Grakatas for being fun.

They sound like a-10 warthogs

The twin grakatas is the best single target primer in the game, and can be built for fairly decent high level DPS with a half decent crit build. Definitely a solid weapon and part of my default kit if I'm ever doing levelcap disruption. Incredibly reliable, incredibly fast, grakata ftw
