It always strikes me to what kind of gas is used to kill Abe in the 'ender' parts of the industrial levels of AE and in RuptureFarms boardroom in AO when the timer runs out.
I believe that the gas is probably
Chlorine, due to the fact that it is poisonous and yellow-green in colour. Also, by the fact that it does not kill Abe instantly, but does kill him in mere seconds.
What do you guys think?
