Is the formula for calculating stage progression available anywhere (besides the source code, of course)?
In a recent game, the humans were at S2 with something like 6+4+2+2+1 kills, and the aliens were still at S1 with many more kills (10+8+2+2+1) - not exact numbers, but that's the flavor of the scores. Someone said the humans got to S2 as a result of many turret kills.
Does dying by "<world>" (as the game log calls it) count the same amount towards stage progression as dying at the hands of the enemy? I could swear I've watched the stage counter not decrement when a human was melted by an acid tube or fell "fowl" to gravity (perhaps version 1.2 will correct the spelling of foul :-)). I've always assumed that turret kills had no adverse effect other than delaying time evos, but if they are pushing humans towards s2, I'll quit attacking turrets with dretches.
