Dota 2 The Defend Final Ending Distruptor

The Dire and Radiant occupy strongholds in opposite corners of the playing field, divided by a river. Within each base is a critical structure called the "Ancient", along with a fountain that regenerates Heroes' health and magic points. A match ends when one side breaches the other's stronghold and destroys the Ancient therein. The two strongholds are connected by three paths, referred to as "lanes", which are guarded by defensive towers and artificially intelligent creatures called "creeps". These creatures periodically spawn in groups and travel along the lanes to attack enemy Heroes, creeps and buildings.[10] Also present are "neutral creeps" hostile to both Radiant and Dire, the most powerful of which is "Roshan", a boss that may be killed by either side to obtain a powerful reward.[11]
