At the start of the game, the war is not going well… the bugs are rampaging across Hesperus - a planet perilously close to Earth. Colonised by man, Hesperus was once a haven of earthly tranquillity. Now, it is a terrifying battleground where the weaknesses of an implacable foe must be discovered and exploited.

Are you ready to join the 'Marauders' - the elite 'Special Forces' of the Mobile Infantry? Can you spearhead the assault against thousands of intelligent enemy bugs? Can you retake planet Hesperus, a Colonized Human mining planet, to save the federation, crush the bug threat and capture the Brain Bug.

Defend your compound against over 300 enemies coming at you simultaneously each with their own AI, using a variety specialist weapons, in these epic battles all made possible by the unique SWARM game engine. It's not been possible before now to put this number of enemies against you all at once.
