So i acquired this great gadget/feature ( whatever you wanna call it) and started using it to pretty good effect. You simply Hold LT to aim and then once the cross-hairs are covering an enemy you depress and HOLD the RB, that's right bumper button. Everything was working out great until a few moments later i tried using it and it simply doesn't work anymore. Whevever i try to fire it/throw it holding the RB releases the normal battarang and i give away my position to everybody making even experimenting with it dangerous and time consuming as i have to deal with enemies after a failed attempt.

Is this some sorta bug or some sorta conditional use feature, as in you must be in one of the predator rooms for the reverse batarang to work, or it can't be used on outside enemies without guns? Is anyybody elese having this problem ? The first time i successfully used it i don't recall the enemy type other then it wasn't a boss. I've since tried it on guys with assault riffles outside and it will not operate in the reverse mode, it simply fires immediately causing my then i have to wait a few minutes to test it again because i have ot reload, fly away and find other enemies.

You need to use the remote batarang not the regular one.

@NinjaHunter: Yeah that was it. Thanks.
