In Jets'n'Guns you assume the role of a freelance pilot who has to save the entire Universe. Your old Colonel, aboard the United Space Ship Impotence, enlists you back into space military to foil the plans of evil warlord Xoxx who has stolen a gigantic space gun with the power to destroy the entire Universe.

This humorous side-scrolling shooter will let the player pilot various space-ships and features upgradable weapons. These upgradable weapons should be used in combination with each other and the player must choose which weapons suit which levels the best. Upgrades also include ship defenses as well as cooling mechanisms and engines. Destroyed ships come crashing down damaging other ships and units on the ground.

This is an expanded version of Jets'n'Guns which features several improvements to the original game.

The main enhancements are the increased screen resolution of 800x600 and the replacement of the text-only mission briefings with comic screens.

Other changes include 21 new levels in the main campaign (the original only had 21) with 70 new enemies including 16 bosses. To fight those you've also access to 7 new ships and 17 new weapons. There are now also secret levels, items and ships waiting to be uncovered.

There's also a new rank system where you can earn additional money and win medals depending on how good you have been in the mission (killed enemies, secrets found and so on).
