900mL of water
The XP 70 is a 1998 XP Super Soaker that holds 900mL of water. It was the medium-sized blaster in the 1998 line, and proved to be very popular. Its good capacity and size made it a good secondary, and it was popular enough to be re-released again in 2004 as a part of the SoakerTag line.
The XP 70 occupies a unique place among all Super Soakers because its water output was defined as the "1x" benchmark by which all other Super Soakers' outputs were measured. If a nozzle was rated "8.5x", this meant that it delivered 8.5 times the water per second of the XP 70. This makes the XP 70 the designated and de facto medium rifle of its generation, and therefore the spiritual if not direct successor the original Super Soaker 50. Its immediate predecessor was the XP 65, and its immediate successor was the XP 270, which was in turn succeeded by the Max-D 5000.
