info_rubble lets you spawn chunks of rubble from a point when triggered. The configuration of the rubble’s appearance and sounds is identical to that of func_breakable, please read that entry for details. info_rubble does not currently support the explosion effect. Because it is a point entity, it also does not support health, it can only be activated by triggering. On the other hand, unlike func_breakable it is possible to trigger the same info_rubble more than once.
