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.
If you see the video there is no way a battery behaves like that, even if you drive a nail into them they more rocket flames than explode (I used to work in a battery lab).
I should clarify, typical cells won’t explode, you could defeat safety features for pressure release in a can cell but at that effort they would have just added something more energetic.
