Hi everyone! I'm not giving tips, I'm asking for them. Anybody here get all three medals for the combat challenge rooms yet? Have any tips for the rest of us? 
 
I'm about 60% thought the main game, and will be needing some tips soon for these rooms. 
 
I've tried them a few times already, and my main problem is keeping the combo going when no one is close enough to me.

When no one is close enough to you try do a ground take down on a fool (also batman can travel an entire room if hes in the middle of a combo). To be really good in the challenge rooms youll need to start using all the moves you can and try have them in one combo. By doing this youll get massive amounts of points, for example when the round starts either strike or counter then evade,batclaw punch fools until you can do a take down or throw then just keep on punchin and throwin/takkedwoning and of course youll have to stun knife dudes. When there only a few guys left throw a batarang which should knock them all down allowoing you to move in for a ground takedown that scores you a lot of points. Although you get  a 1000 point bonus for not breaking your combo in a round you should be more conserned about your variation bonus, I got really tied down trying to do flawlessly in each round which is nigh impossible@trustymutsi:

I should try these, im not very good at the combat rooms. The predator rooms on the other hand, lots of fun and relatively easy(imo).

Use every single one of your abilities in a combo or as much as you can, that'll rack up tons of points. Evade ALOT. You can evade multiple times and still keep the combo going, so I'd usually evade until I'm not surrounded. Abusing batarangs on the extreme levels are really helpful.

Great, that helps guys! 

Use throw a lot...just try not to ring out guys, it doesn't give a lot of points and removes a target to be slapped around a few more times for a higher combo. 
For Knives and Tazers ignore stun and just flip behind them and continue the combo, as mentioned if you can isolate an enemy and do a Ground Pound at 10+ combo you'll be getting 1000+ points each time you do it, it's a very very good way to end a round. 
 
I would also suggest having full combat upgrades, critical hits essentially double your combo if you're timing your punches right and being able to do throw/takedown at 5-Combo instead of 8-Combo will greatly improve you chances. Again try not to ring out or throw guys into electric barriers, will kill your points for beating them with your hands.

Variety Bonus. 
 
Seriously, if you use all your moves every round that's 5000 a round.

• Try to stay in combo state
• Don't take any blows
• Don't mash buttons
• Variety in combos gives up to 5k points (use counter, stun, baterang, batclaw, combo takedown, combo throw and ground takedown in one single combo for full points)
• When the room clears up, use baterang to send as much enemies to the ground as possible - then use ground takedown for 100 points X combo-rating (massive points incoming)

Ah, that's where I was going wrong - I can get a perfect freeflow combat award on every round but never a high variation bonus - I rarely counter if I'm concentrating on getting the batclaw/batarang into use.

Even then, I've got all 3 stars (or bats) on every challenge room except the one with the two titan henchmen at the end. I just don't know what to do with them... I hate that I automatically climb on them and can't get down - if there's a guy with a gun across the room, you'll never reach him before he kills your combo

 hope these can help anyone struggling on these two which are by far the hardest imo, shock and awe extreme and rumble in the jungle extreme
 
I did shock and awe extreme by getting really great scores on the first three, it is far easier to keep within the time limit on these three. Put all your efforts into getting high scores on these as the fourth is very hard to score well on.. you need to give yourself some breathing room so that on the 4th you can just concentrate on getting your combo meter up to 5 and then instant takedowning (b+y). No variation bonusing, just get your combo meter yellow then take an enemy out.. only real way i could get under the timelimit. Get your x5 by beating on non-knife/eletric guys, then go for one of the knife/eletric guys with your instantTK. Very frustrating when you get to 30k in the first three rounds, only to run out of time on the fourth!!
 
Rumble in the jungle extreme.. stop guys from getting boxes and guns, just listen out for the alarm at all time and watch the boxes, they're your priority. Also learn to evade away into some space if you're beginnig to get surrounded, you can keep your combo going if you hit someone soon after. RITJE is all about the tank guys though. Get a nice combo going, tthen evade using an enemy (so your combo is still going strong, evading normally gives you less time to hit the next person) when a tank comes, of course, that's after hitting tank with batarang. Now get in there and punch him enough times to get him grounded, but countering the other guys is priority because you can stop pnuching tank and he'll still be dazed after you counter an oncomer. When he is kneeling/grounded.. stay away from him. If you've managed to get a x10 by this point, this is your chance to hit the big points, as he'll be down for some time, get your combo up another 10 or so, as much as you feel safe doing.. THEN jump on his back. You could be on x20 before you've even started thwacking guys on his back.  When i finally did it, i got 17k on first round (by far my best, this is really what won it for me, can't expect to do that every time.. 12k is really what you want to go for), 20k on 2nd, 10k on third, 10k on fourth.
