Challenge Mode

Unlocked by completing the main game for the first time, this mini game is all about Weapon Break maneuvers, in which the protagonist (Lenin or any of his brethren) must dispose of numerous enemies without taking too much damage.

In most scenarios, the protagonist will be equipped with the standard weapon, often using polearms (most frequently naginata) or other optional weapons as specified. 

Furthermore, certain scenarios are made more challenging due to the primary defeat condition (the damage threshold).

The enemies are armed with machetes or ninjatō/uchigatana, which have their blades broken/shattered by the protagonist’s melee weapon, thus getting themselves butchered in the process.

In the mini game set during the Lizardmageddon, the enemies wield combat knives and/or machetes against Lenin.

The combat knives do 6 points of damage, whereas the machetes do 8.

In minigames subsequent to the Lizardmageddon, the antagonists (often) wield actual swords, which range from uchigatana to dadao.

However, Lenin is still better armed than the enemies.
