6 x Science Pack 1
2 x Science Pack 2
1 x Science Pack 3
= 1 x Alien Science Pack
54 x Science Pack 1
27 x Science Pack 2
9 x Science Pack 3
= 1 x Alien Artifact
v0.1.2: Fix to work on current version.
v0.1.1: Now requires tech to be learned, may need new game for this one to take effect.
v0.1.0: Updated for 0.13, added graphics to research icons.
v0.0.1 - v0.0.6: Originally made by darkrising, I take no credit other than uploading since he is no longer active. Original mod found here: https://forums.factorio.com/viewtopic.php?t=3373
