Replicator

The eggs keep hatching... the bugs are out of control... it cannot be done... its insane! Hold down the X or Z key for rapid fire in different directions. Destroy the bugs before they hatch more eggs. And remember... “the only good bug is a dead bug”.

Replicator was designed by Brent Silby in 2004. It was coded in Javascript, which was unusual at the time, given that most browser games in that era were written in Flash.
