its been a while since ive played halo 2, these may be a little wrong

• run up to wall and look down and enemy cant see you because your head is in wall
• double tap Y when the mag gets put in the gun to reload faster (this also works in halo ce)
• iirc if you cloak and then enter a vehicle you still have cloak
• if you make an elite outside hotel zanzibar mad you can kill him for energy sword
• at the very beginning of outskirts you can jump on a light up to the roof and then grenade jump up and you can jump across rooftops to skip the a chunk of the level
• sniper jackals dont have perfect accuracy, i dodged a few shots one time
• its best to attack the sniper jackals either before/right when they see you or after theyve shot twice
• on the original xbox version you can go through walls if you hump a box around 8 times (you should see the camera jump a little each time if you did it right)
• in that snowy arbiter level near the end with flood everywhere you can wiggle the ghost into that burnt wreckage area
• throw grenade when you punch regret
• i think sometimes the flood get stuck in the pits they spawn in
• when elites (including ones with swords) try to melee you, you can dodge it and backsmack them but iirc their melee hitbox is kinda janky and big
