During the gameplay I noticed that Chief appeared to be slow when running, sliding and grappling. It felt like he was Nurfed due to the armor possibly. I hope he was just slowed down for the Showcase. I want to play at a similar speed to the Doom Slayer but for Chief’s running, sliding and grappling.
Another gameplay mechanic is the use of " Tools " that Chief can equip to himself. Very much like the Doom Slayer, Chief needs to be very powerful in this next title for us to experience a Spartan’s true battle prowess. So, maybe 3 grapples, suit upgrades to increase Shield Recharge rate or More Inventory space.
This was just what I want to feel and have when I play as the Master Chief. Thx for reading this simple speculation on the game.
