A few things I don't recall being mentioned when discussing the gameplay are that stealth takedowns and combo moves. Did you know that the powere meter that fills up bellow Batman's health bar enables you to perform a special move to save your bacon and take down a significant portion of your enemy's health bar. There are five available and you unlock them the more points you earn from completing levels. The last move you unlock is by having perfect scores on every level. Luckily it's automatically perfomed when you defeat Joker the first time. The Arkham games had a similar mechanic with the score multiplier to perfom a combat takedown or disarm during those freeflow combat sections. The stealth takedowns can performed if you have handcuffs in your utility belt and if you successfully sneak up on a guard and push the interact button you can handcuff a guard without fighting them. I only successfully performed those takedowns twice without using smoke bombs or the invisibility cheat. One of those times was by accident. Yeah, if a guard spots you and you disorient them using a smoke bomb you can sneak up behind them in the smoke to take them down. Definitely another thing the Arkham games borrowed from this game. Since I mentioned cheats, there are five cheats you can unlock in the game. Three of the cheats are found in hidden locations and two of them require a gliding challenge to obtain. All five them are in shiny envelopes. The cheats are unlimited gadgets, unlimited handcuffs, unlimited power meter (combo moves), unlimited health, and invisibility. The cheats become available when you complete the game and if you collect the envelopes. You can unlock the missing cheats by revisiting the levels after beating the game using the cheats you unlock. I wish the cheats applied to the vehicle levels.

Yes, the Gameboy Advanced version is a very different game than the GameCube, PlayStation 2, and Xbox versions of Batman Vengeance. It follows the same story as those versions, but it's gameplay is more akin to the Adventures Of Batman & Robin. It's basically Ubisoft's second attempt to make a New Batman Adventures version of the Adventures of Batman & Robin because their first attempt was the Gameboy Color game Batman Chaos in Gotham where it's a side scrolling adventure game. The Gameboy Advanced version of Batman Vengeance includes appearances from Robin and Nightwing as opposed to just being Batman and Batgirl. Also Harley Quinn is given an actual boss fight in the game, it's one of two Batman games to make Harley an actual boss the other being Gotham Knights, I don't count the predator boss from Arkham City's Harley Quinn's Revenge DLC. I do find it hilarious that the sequel to Batman Vengeance, Batman Rise of Sin Tzu, includes Nightwing, Robin, and Batgirl as playable characters, only for the game to solely focus on Batman, none of his allies appear in the cutscenes just Batman & Gordon. I do like that Joker, Harley, Ivy, and Freeze appear in the Rise of Sin Tzu as connective tissue to Vengeance. I will Rise of Sin Tzu has wildy different gameplay opting for a beat em up instead of the action adventure game, which works for the co-op mode. If only the cutscenes acknowledged it was a co-op game. That's a game for another episode. Lastly, the podcast the DCAU Review did a Black Friday special on DCAU video games and they ended it with a top 3 DCAU games Batman Vengeance (PS2, GameCube, and Xbox version) was in their top 3 with Superman Shadow of Apokalips and The Adventures of Batman & Robin.
