Batman: Arkham Asylum Hint: "Night Glider" Achievement / Trophy Made Easy
Climb to the highest point of Arkham Mansion in Arkham East (the clock tower) and glide down for an easy Night Glider Achievement / Trophy (Glide continuously for 100 meters).
Batman: Arkham Asylum Hint: High Combo Hint
When you fight a Titan henchman and a group of normal henchmen, stun a Titan, jump on his back and used him to hit the normal baddies. Your combo total goes up even you didn't hit anything!
Batman: Arkham Asylum Hint: Catch! Achievement / Trophy
You'll need to catch your own Batarang for the Catch! Achievement. To do so, head outside of a building and, with the Remote Controlled Batarang upgrade, toss your Batarang, Control it so it returns to Batman in a wide arch to satisfy the Trophy / Achievement requirement.
Batman: Arkham Asylum Hint: "Freeflow Perfection" Achievement / Trophy
Before attempting this Achievement / Trophy you should have Batman fully upgraded with all combo-based upgrades etc. You can do this fairly easily in the later rounds of the first Challenge, Intensive Treatment. You'll need to perform the following moves in a single combo (don't get hit, or blocked or let the combo counter run out) to get the Achievement / Trophy. NOTE: You can Evade as many times as you want to keep your combo going!
- Quick Batarang (may NOT be necessary)
- Quick Batclaw (may NOT be necessary)
- Punch
- Stun
- Evade
- Counter
- Throw
- Instant Takedown
- Ground Takedown
Begin with the Batclaw and follow it with a Batarang -- these may not be necessary but you may as well throw them in since they won't hinder you at all. After using the first few moves listed after those, plus a couple of Punches to get your combo meter above 5x, you can perform a Throw. Don't let him hit anyone else or you may leave yourself without any opponents to continue the combo.
Punch a bit more and Evade as needed, then use the Instant Takedown when its available. Before using a Ground Takedown to complete this combo, use some Batarangs to stun anyone else nearby -- if it's all clear, go for the Ground Takedown to complete the "perfect" combo!
