"Try this little trick to share the wealth with your whole team.  Whenever you find a canister, position your entire team next to it and then pause the game by pressing [Space].  Select each hero in turn then right-click on the canister and select the 'Use' command.  Once you've done this, press [Space] again.  All of your heroes should grab the canister at the same time and all get the bonus!" - TEM
