Acrylic didn't work. So I've dome some custom tokens, printed out on a colour printer and pasted to 3mm foamboard.
Some examples here - and the tokens in use for a CoZo game.
Note that I've produced some specific items such as Alien Control (for a specific scenario where an alien had mind control over people who came within a certain distance) and Radioactive (nuclear power plant leakage causes havoc - and zombie infestation).
The skull rock is actually a cunningly disguised satellite uplink that the Grymn are defending against the automatons.
