Reading the Wikipedia article on the CPS 2000 it claims the CPS 2000 started the 3rd era of water warfare. here is how I define era's
The age of Squirt Guns and Balloons 1960's-1990
This age was when water fights were just starting to become a hobby, water guns were weak (even by modern standards
) and although their were entertek blasters they were few and far between.
The dawn of the Super Soaker 1991-93
Water fights had by now been raging for 30 years with little change in the weapons. The closest thing to domination was the bucket/hose and use thereof was strongly frowned upon. Then the Super Soaker 50 came on the scene with a splash changing water fights forever.

Super Soaker 100
The rise of the XP's 1993-1995
The Super Soaker 50 had been dominating water fights for only 2 years when the nature of water fights changed again, as the Super Soaker XP 300 jumped the gun a full year on the other XP's but without the XP in the name, when the other XP's finally arrived in action they instantly earned the fearsome reputation of the 300, and won plenty of fans.

The golden age of water warfare 1996-2002
The golden age started off with a bang as the CPS 2000 came onto the field for the first time. Other ages had had their share of Champions, but wow what a gun boasting 30 times the power of the 50. In the next 6 years water guns would be pushed to the practical limits of what kids could wield and beyond.
Age of Community water warfare 2003-present
In 2003 Hasbro made the dreaded EES line, marking the end of 12 years of constantly improving water guns. It also marked the launch of SScentral.org and Waterwar.net the first real community's. Although their had been a rather large group on "Aquatica" these had disbanded for reasons that only M4 and Isoaker would know of. The Original Super Soaker designers lost their brand recognition, slowly making ground in the market and hoping for a chance to make large guns like the 2500 and 2000 once again. fired by the very company they had built and forced to start over under the name of Water Warriors.
