Warframe - Online FPS/RPG with Mech Suits that is F2P on Steam

Anyone tried this game out yet? Its Free on Steam and in Open Beta. Basically you get to choose between a variety of armored suits called Warframes. The Warframes look and feel like you are a ninja or samurai in a futuristic space setting.... each frame is different like light or heavy armor, with different loadouts or specialties like long range snipers, mid range machine gun/pistols, melee combat, speed + stealth, ect. It's mainly a shooter type so you have a large gun and hand gun, plus a melee weapon. You can focus on shooting or using melee to kill enemies, plus you get special powered abilities to help kill multiple enemies, as well as CC like blinding aoe flashes, or boost your stealth/speed/jumping skills to play the way you want to play, esp based on the specialty of the Warframe. You run around in "dungeons" doing various missions, killing enemies and bosses, and collecting various loot like new weapons, mods to upgrade your gear or armor, and mats/blueprints to build stuff.

I just started it recently after hearing about it on Reddit......its pretty fun (tho a little repetitive) and has potential to be a pretty good game. It's a little like diablo as far as doing runs for gear and upgrades, with alot of customization and its a FPS so a little different from your typical action rpg.

Also....if there is anyone here who has already played it, let me know cause I'm curious what more experienced players run with for their warframes, guns and mods and what they do in game....like what planets/missions do they farm and just general tips/advice.
