Elum trap:
I think that the PS version had only Black bombs, PC has boths. (I played AP once with white bombs and once with black)
Yet I still wonder what caused 2 versions.
Also, about the older, Unfinished versions. Were they released somewhen? who had them?
And for the last question, where can I check if my AE copy is up to date and where can I upgrade it to the latest version?
