Continental Supplies is a game mode created by Vatten long time ego. It's distributed with the game. It has some new fun scripted weapons and broad spectrum of tactic possibilites but basically noone is playing it because very few people know how to do it (similar situation to mutant some time ego). Here's all i found out about this mode.

First remember - all special weapons and continent selection are activated with "switch hog" key (default: tab), you can also switch backwards using shift + tab. Eg. lets say you're playing North America, you can choose sniper, press tab and fire "Green lipstick". Read the messages at the top to know what mode is activated.

You can check the description of currently active team by pressing esc.
At the begining of first turn you must choose 1 of 9 continents. Choose wisely because you're stuck with those weapons throughout the entire game. Mind that you can check the inventory while you're browsing the continents (just click right mouse button).

Hammer: Flare: fire up some bombs depending on hogs depending on hogs in the circle
Hammer: Lonely Cries: Rise the water if no hog is in the circle and deal 10 damage to all hogs
