Aditya Ravi Shankar built the clone as part of his attempt to improve his coding skills, where he gave himself an entire month to do so, building the game in the browser while going through the original game’s files in order to get sprites, sounds and specs just the way it was. According to Shankar, “In hindsight, I might have wanted to take smaller steps and make a tower defense game instead of jumping directly into an RTS. Trying to do the whole thing in under a month all by myself wasn’t the smartest idea.”
Still, he got the job done, and there were some glitches here and there during testing, such as tanks getting stuck in the sea, and it works best in Chrome or Firefox. If you want to help improve Shankar’s work, check out the source code here.
