Norway is the 6th stage in Into the Future.
|Into the Future - Stage 6|
Those Guys appear as peons.
Hippoe appears as a weak support.
Hyppoh will appear as the main boss. It is a very strong alien, but gets weak later on. (Also, multiple Hyppohs will spawn in chapter 3!)
For chapter 1: Hyppoh is a very dangerous enemy with its 700% stat buff, so you should take caution. It has somewhat long range, fast attack rate, high health (Half of that of The Face without treasures) and high damage. To beat Hyppoh, you should stall it and hit it with hard hitters, like Mythical Titan Cat or Dragon Cat. Anti-Alien cats help immensely here.
For chapters 2 & 3: Hyppoh shouldn't be a big threat anymore. Just spawn Jamiera cats and other hard hitters to deal with the Hyppohs easily.
