Assault Suits Valken[a], also known as Cybernator, is a 2D mecha action game developed by Masaya and released in 1992 for the Super Nintendo Entertainment System.

The story follows Jake Brain who pilots a giant mecha and fights in a war engulfing the entire world.

It is equipped with a variety of weapons and other special accessories, giving it full land and minor air capabilities.

Jake and his platoon, which operate from the warship Versis are tasked with destruction of Bildvorg, the most powerful mech of the Axis forces.

Ironically in that mission the player saves an enemy suit entering the Earth's atmosphere, whereas Beldark kills Jake's ally Apollo soon after.

In Assault Suits Valken 2, Jake makes a cameo appearance as a 30-year-old veteran soldier who assists in battles as an NPC.

There is also a scene absent in which the president of the enemy forces, whose banner is that of the European Union, after realizing that his nation has been defeated, commits suicide.

Also some written dialog is taken out, which shows the soldier rescued in the fourth level being in the robot fought before the final boss.
