When Alphadin says 'he' made them he means that he stole the set of player types I gave him as a reference for how to make regenerating health.
Regulith, did I give you my edited set of TF2 Player Types already?
EDIT: It seems not. I'll release them here. They're pretty much based off the existing ones posted on the forums (so I'm not releasing officially as an Add-On), except with scaled down health. 125 health in TF2 -> 100 health in Blockland. The Medic has regenerating health, the rate increases after a few seconds of not being hurt and the Engineer, Sniper and Spy types have been combined into a TF2 Standard set. Each has a lower jump height (in particular allows the Demoman's jump to stay within the sticky-bomb blast radius and jump correctly) and are balanced with the weapons I gave you.
