Achievement Atlas.
It looks a bit like... a school yearbook?
The cover has a nice texture, and it's unclear what material it's made of. Flipping to the first page, he sees three diamond-shaped holes on it.
One is completely lit up, one has a faint white glow, and the last one is pitch black and has no light at all.
"Achievement Name": Ultimate Massacre.
"Trigger Condition": Kill 50,000 Alien Races in one minute, kill 100,000 Alien Races in one minute, kill 200,000 Alien Races in one minute.
"Completion Degree": All three levels are lit.
This is the first hole, and the only one where all three levels are lit up.
And the faint white light below is...
"Achievement Name": Slaughter Machine.
"Trigger Condition": Single Day Slaughter of 100,000, Single Day Slaughter of a million, Single Day Slaughter of 10 million
"Completion Degree": First level lit up.
