Tony stated the following, “A lot of the cheats we see in fighting games are either about reading inputs, reading game state, or injecting inputs. They involve modifying the game binary in some way. Vanguard is really good at that, right? It’s a kernel-level anti-cheat, so it can detect and prevent a lot of those things happening.”
Humble bundle does still give to charity. The default they give is usually extremely low but on bundles you can adjust the sliders though they’ve now hidden it underneath the purchase button.
Edit: looks like the old series x was 499 but is on sale for 449 basically everywhere. The new discless series x is 449, but will prob be on sale for 400 in a few months.
