Relatively short lived chemical power ups for Japanese, Soviet and German soldiers. Note there is some overlap in serums so there isn't 101 different effects (more like 50ish). With proper visial effects, this should help scare your players.
I wish there were more serums and less overlap.<br><br><b>QUALITY</b>: Very Good<br><br><b>VALUE</b>: Satisfied<br>
