To give gamers more power in the game, the developers have added tendrils. Tendrils sprout from Heller's arm and can be used for a variety of purposes. Players can use tendrils to smash objects into other objects, such as a car into a tank or vice-versa. Also, players can string up enemies in "webs", much like the abilities of Spider-Man, to make them vulnerable for further attacks. Players will be able to dismember enemies, a force that will become more useful as the game progresses. There are many more ways to kill enemies, ranging from throwing a tank at a group of Blackwatch soldiers, hacking off a mutant's head or using the tendrils. When the player picks up a person, the game will no longer automatically kill them, starting a combat sequence, Radical has tweaked this to become a useful tool, an intimidation factor.
Heller will not be given his missions by a person, but rather choose them himself. Hacking onto Blacknet, Blackwatch's system that details military operations and the three areas of NYZ, Heller chooses his own missions. Blacknet will allow Heller to find operations that he can disrupt or take control of for his own purposes, or find important people that will allow him to learn more about what he has become because of the Blacklight virus. It will also help him find out more about Alex Mercer and what his connections are to his family's deaths. The missions that are selectable can be sidequests or extensions to the main quest that tell Heller more about the Blacklight virus.
