Hiyas!
In the original Chaosium game, groups of investigators could "gang up" on critters/gates... For instance, if a Gate appeared in the Black Cave, several investigators could help close it - all at the same time, in the same location as the Gate; or, if a Cthonian began wandering Arkham's streets, a group of stalwart investigators could try to destroy it - the monster & the investigators - all in the same (combat) space.
Can this still be done or is it just one investigator per monster/gate at a time?
Thanks!
