The suitcase is an item that can be found in the northern part of the map once Jokke has revealed that he's a millionaire while giving him a ride home at the 5-6th time. The suitcase can be opened by pressing F while looking at it, revealing around 2,000,000 mk.
There are drawbacks to this hefty amount of money though; the whole sum cannot be taken out at once, but rather at a rate of 100 mk per click, and more importantly; sleeping in the bed at home will make the player wake up to Jokke standing at the doorway with an ax, ready to murder the player.
