Guaranteed to work! I had fun killing Walter around 8 times in the Forest World while losing around half of my health bar, and that's because I was experimenting with other weapons too (Stun Gun, Chainsaw).Kick Walter’s Ass! v1.0
I've finally figured out a way to deal with Walter while taking minimal or even no damage. Two key things you have to do before you take him on:
1. Find the Spade in the Building World, 1st time. It can be found by taking the elevator back up to floor B8 after the cutscene with Richard and Little Walter. Go up the north door according to your map, and you’ll find a twisting hallway that will eventually lead to a Sword of Obedience and the Spade at the end. Watch out for Peter Wolls’ ghost though.
This is the best anti-Walter weapon in the game period. If you’ve noticed, he won’t move an inch at regular standard attacks with the exception of the Pickaxe of Despair, but a charge up attack from most weapons will make him flinch over in pain. This is where the Spade shines the best; with its speedy charge up time and great reach, it's perfect for socking the punk in the blue coat repeatedly without worrying about him retaliating.
If you didn’t find the Spade, don’t knock yourself on the head yet; the Rusty Axe also works beautifully, it just has a slower charge up time. If you don’t have the Rusty Axe either, then you might as well run away from Walter because trying to score a charge up attack hit on him with other weapons is extremely difficult.
2. Ditch Eileen. She’ll only get in the way, and you don’t want to risk her getting injured by not only Walter but from yourself as well. She might decide to run up and bop Walter on the head with her weapon just when you thrust forward the Spade, hurting Walter AND her.

Key Walter tactics
1. Get up close to him. The more closer you are to him, the more likely he’ll use his Steel Pipe or Chainsaw to thwack you. You want him to use the melee weapon, because if he uses his pistol he will shoot you repeatedly, making you flinch in pain and lose a bunch of health while he laughs at you. If he runs away like a little girl, chase him down and keep a safe distance.
Another added bonus is that if Walter does decide to draw his pistol, you can simply run right behind him and he’ll change his mind about shooting you. It’s easier to run around Walter if you keep the radius distance between him and you tight.
2. Know the distance of your charge up attack, and keep just slightly enough in range that the tip of the spade should poke Walter. Right before he attacks, walk up to him a little closer so you’ll guarantee yourself a direct hit.
It’s not necessary to wait for Walter to attack and then stab him right after; performing your charge up attack gives you temporary invulnerability, so keep on jabbing him whenever you can. Just don’t get too careless, or he’ll hit/shoot you before you have time to let go of the attack button to perform your move.
3. Hop back if he decides to hit you with his melee weapon. The hop is extremely useful for dodging his melee attacks; if he decides to take a swipe at you, simply hit the Square button while readying your weapon and Henry will do a backwards hop. Be sure to walk back to Walter as soon as he’s finished attacking.
