In no particular order, here's a list of the pairs of augmentations that were used in the real game. These are the values that you type in the AddAugs properties of an AugmentationCannister actor. There's nothing to prevent you from using other combinations, or even providing only a single aug in an augmentation cannister, but the augs were designed with these pairs in mind.
