Warframe Mars - War (assasination mission solo LT Lech Kril kill ) 

Maybe because they think it's just a "NOOB" gameplay in a lot... But this is a "how to first solo killing" walktrough video and NOT a "solo, endgame-geared, overpowered, world record, speed boss farm" video. (I think the first successful boss killing is always the hardest challenge and the second is just a repeat.)

Thank you, but I just using what I find... it is possible to kill every boss alone. (at the end of the video, I've shown all the used mods)
