Yeah they added “action keys” that can trigger different percentage presses (20-40-60-80-100%) as a “fix” because the bobsleigh blocks they added in the new game were not keyboard friendly and they wanted to even the playing field. They eventually changed the physics to get rid of that specific need (but not completely) but they are still useful in some situations.
Download the newest game! It has a free access tier which gets you access to the first 10 tracks of the quarterly campaign and to the ranked mode. It is a bit limited but enough to see if you might get back into it. There is a decent community on reddit for the game.
Hi-Rez and shutting down games, name me a more iconic pairing.
