And Tal, to see the laser shield in action type jjshield four times. And apart from the laser shield and the fast feet there are some other events in JCS that do nothing, such as the springcord, max weapon, auto fire - or its functionality is hidden, though I highly doubt it. [offtopic] There will be some good use for these events, however, in the next version of my program Toolbox. [/offtopic]
