For 9 instalments, James "Decent Jam" Parry has been leading Team PTC through ever more challenging operations, training up an elite group of soldiers and researching advanced alien technology.
This latest episode marks the beginning of the end. Either the end of the invaders' campaign against us, or the end of humanity as we know it.
The enemies have grown tougher over time, with new units being deployed in an attempt to thwart the plans of PTC. However, the team have grown stronger too. Utilising the technology of those who would destroy us, our Commander has crafted weapons and armour that are far superior to anything previously found on our little planet.
Will our advanced hardware and James' tactical nous be enough to push back the alien threat for good?
