In Deus Ex: Invisible War, there are only upgrade canisters to be found (except they are not called that, they are just called biomods). There are two types of biomods, regular and black market. These cannot be mixed in a particular augmentation slot, although you can have some black market augmentations and some regular augmentations. There are six slots. The first slot (F1) only contains a Light. Biomod canisters cannot be installed in that slot.
