The Enlightened faction believes that XM, while potentially dangerous if misused, is critical to the advancement of our species, and that the Shapers are a benevolent species who wish to help humanity. They are represented by the color green and the abbreviation ENL. They generally view artificial intelligence as potentially dangerous to the future of humanity if not carefully controlled. Their logo is a stylized eye with four rays emanating from it. Enlightened agents are nicknamed “frogs.”
The Resistance faction believes that XM is dangerous, or at least not sufficiently understood to merit exposing people to it. Many Resistance agents believe that the Shapers intend to enslave humanity, although some think that they may be benevolent but misguided. Some welcome the N’zeer, who have been opposed to the Shapers. Those affiliated with the Resistance generally hold artificial intelligence as being the key to humankind’s advancement. They are represented by the color blue and the abbreviation RES. Their logo portrays a key enclosed in a shield. Resistance agents are nicknamed “smurfs.”
Choosing a Faction
New Ingress agents are required to choose a faction. While it is possible to change factions later, doing so requires a delay of several weeks and erases your inventory and AP, so it is best to choose with the intention of sticking with that faction.
Both sides have the same in-game abilities, and the storyline is careful to ensure that neither side is unambiguously good or evil. Therefore, your choice of faction comes down to personal preference. If you have a friend who is already an Ingress agent, you may want to choose the same faction as them so that you can play together. (Or, if your relationship is of a more competitive nature, you may opt to join opposite factions.)
Without a friend who is already an Ingress agent, many agents choose the faction whose philosophy most closely mirrors their own. Some ask around to find out which faction is the underdog in the local area and choose based on that. Some just go with their favorite color. Ultimately, the faction you join is a personal choice. Only you can know which one is best for you.
