You have fully robotic exo-skeleton hands that have a functionality similar to Iron Man from the Marvel universe, namely: to make repulsor shots, as well as to create a powerful charge of energy in the form of lasers.

With the help of your superhuman abilities thanks to your exo-hands, you have to survive in the endless fields of the apocalypse, full of crowds of zombies. Also, in the Deffort mode, you have a cold fusion reactor that does not allow the zombie virus to defeat you. In the Hallway Adventures mode, you have to clear rooms from zombies, and Deffort is a Tower Defense mode where you need to buy upgrades for your reactor and protect it from zombies who are drawn to cold fusion.

Also use passive and activated abilities: passive ones work, oddly enough, passively, and activated ones can be activated.
