Watching, Waiting is a skill that grants a bonus to attack and power armor. Entering stealth doubles that bonus while also healing the Caped Crusader over time. Battarang is a skill that throws a single blade at an enemy, dealing damage and marking the target for a short time. Martial Arts allows Batman to leap to his target, dealing attack damage and activating the stun of Battarang.
To see these skills -- as well as Batman's ultimate skill and some helpful tips for playing Batman effectively -- check out the full video just after the cut. And if you'd like to get your hands on Infinite Crisis yourself, the beta sign-ups are still open.
