Kill a teammate with friendly fire off.
Dirty Bomb Challenges
Get a triple kill with 1 Arty Strike (Oh wait arty strike doesn’t 1 shot kill last time i checked)
Plant a c4 that kills at least 3 enemies (I’ve actually gotten a quad with a c4 as Sawbonez before, 2funny)
I usually don’t promote drinking but Nader “direct drinking” game.
Take Nader, grenadelauncher only.
Only direct hits are good. Everytime you miss a shot take a shot (or whatever you prefer feels appropriate, drink responsible and all that).
Athletic variant for healthgurus, underage persons, pussies, recovering alcoholics.
Replace alcohol with push-ups. Thats how I stay fit (not really).

HERE IS A CHALLENGE…
’ True Definition of a ninja’…
Some extra stuff 
-No Supporting team mates near you !
-No underground
-Must have enemies that are ‘alive’ and can respond to you.(infront of your or side of you or something)
-You know what ninjas do … Get behind em n plant the c4 !
(if you want look extra cool,try it without using engineer)
Td;lr - Plant C4 while enemy is alive and the enemy is standing near you !
(There are 4 enemies alive in my pic(1 dead), 2 you can see in the pic and 2 are on the far right side )

Oh uh I already did that unintentional by the way…
One of those clips show me as sparks, planting behind the enemy team on Underground.
Or this one, a entire game of Agent Sparks master ninja 
Oooh damn i forgot to say underground doesnt count in this challenge …
Underground is too easy to ninja plant…
I do that almost everytime(sometimes c4 would get defused n me killed)… Be ready and be half way across the map while the first thing explodes… In a few mins, the 2nd one will explode !
pretty sure most players do this on regular basis !
Try it on another map please

Okay 
[quote=“Zita;31972”]Using BushWacker.
Map: Trainyard, Stop Watch mode.
Goal: Do all the objectives your self (not letting team members do them) in under 10 mins, so lay both c4’s and return both samples, and win the game.
BushWacker has to be used in both parts of the game.[/quote]
Why is that considered a challenge?
Done it myself, currently my fastest time on Trainyard with bushwack.
