Some time ago, Earth was overrun by aliens, but suddenly they all left leaving no trace behind. At least that's what the public was told, but in reality the purpose of the invation was to hide three giant alpha aliens in different places on the planet that would take over Earth from the inside. BROFORCE has recently discovered the positions of these alpha aliens, but a group of terrorists has too and they are gurding them, hoping that they will benifit from it in the long run. Your mission is to get rid of these alpha aliens before they begin to infest the planet with smaller aliens again and finally put a stop to the aliens by traveling to their home planet and LIBERATING them. You know what to do, BROS!

This campaign is ~22 levels and it is my biggest one yet. It is split into 4 "worlds" that each have a different theme and gameplay focus (Vehicles, platforming, missiles, aliens). It took a long time to make and i put a lot of effort into every part of it, so i hope you'll enjoy it. ;)
