- SMART is completely optional. Everything that you can do with smart, can also be done manually using standard run, jump, and crouch buttons.
- The level designer’s didn’t set up specific spots for players to use mantles, vaults and slides - the system simply pre-calculates where they’re possible.
and
- The SMART button is actually a very simple concept. You hold it down, and that means you’re signaling to the game that you don’t want to get stuck on anything. If something gets in your way, you will climb over it, slide under it, or smash through it (in the case of enemy players).
= (hopefully) no getting gayed by autoclimb. Hopefully the damage models follow the animation properly when using SMART (and don't get distorted or lag behind the player).
