Decent time-killer with terrible devs attached. Several people I know got banned with no appeal for no reason after sinking tons of time and some money into it.

Surprisingly fun, though way too easy.

Good in the same way neverending grinding to get XP to level up to fight more level upped enemies with no gameplay, cool wall running and fremium player skins is good.

I've been playing this off-and-on since the beta, and this game is a testament to how well a game can be concurrently developed through consistent user feedback. That being said, however, it is still GrindFrame. Grind the planets to get the materials to craft your guns, then grind for the next thing whilst you wait 12-24 hours for the thing to craft. And don't get me started on hand-crafting frames. 3 pieces at like 12+ hours each, then combining them is 72 hours? Aight. I'll play something else

fun enough for a free-to-play game.

I'm changing my review. This is a good game with a lot of content and some pretty interesting depth in the progression (though not my ideal form of it). The combat is fun, fast, there's enough variety in mission types to be fairly interesting, the warframes are neat... but it's still too much of a grind fest. Sure, there's a story but who cares? This game requires more time than I'm willing to give it to go into detail but I think that's a decent summary.
