Weapons are XMP Bursters 
, Ultra Strikes 
and Flip Cards: ADA Refactors 
(for flipping Enlightened 
Portals to blue) and JARVIS Viruses 
(for flipping Resistance 
Portals to green).
Weapon Items
| Item | Rarity | Description |
|---|---|---|
| XMP Burster
|
Very Common (L1 - L8) |
High range and damage, but not so good at destroying Portal Mods (e.g. Portal Shields  ). The most common weapon item.
|
| Ultra Strike
|
Very Common (L1 - L8) |
Low range, high critical hit chance. Ideal at destroying Portal Shields and other Portal Mods. Occasionally useful for taking out individual Resonators  .
Although marked as "Very Common", these are dropped much more rarely from hacking than XMP Bursters |
| ADA Refactor
|
Very Rare | Used to flip Enlightened -owned Portals to Resistance control; can be used by both factions.
|
| JARVIS Virus
|
Very Rare | Used to flip Resistance -owned Portals to Enlightened control; can be used by both factions.

Mechanism
The below describes mechanisms shared by XMP Burster and Ultra Strike .
Damage
The damage model is well-understood thanks to data collected by Copenhagen Resistance players. The full range of the Weapon is divided into equal fifths. Resonators that are 0-20%, 20-40%, 40-60%, 60-80%, and 80-100% of the weapon's maximum range receive 100%, 50%, 25%, 12.5%, and 6.25% of raw damage respectively. (The raw damage, of course, may be further modified by Mitigation and Critical Hits.)[1]
Critical Hits
Whenever an XMP Burster or Ultra Strike damages a Portal, there is a small chance for it to deal double damage. These critical hits are indicated by an exclamation point appearing before the damage indicator.
Critical hits can also be scored against Portal Mods. Mods are only destroyed by critical hits, so whenever a +80 AP appears, it means that the Agent has scored a critical hit on that mod. Stickiness gives a Mod a chance to survive a critical hit.
It is unknown how critical chance is calculated. User observation suggest that the chance for a Resonator or Mod to receive a critical hit is higher with:
- Lower range to weapon detonation point
- Longer charge-up before firing
- Ultra Strikes
Stacking
While XMP Bursters and Ultra Strikes will only fire individually, multiple such weapons can be queued up by firing in close succession. These will fire as the Ingress server processes the effects of previous attacks. Only a certain amount of XMP Bursters or Ultra Strikes can be stacked at once, if the upper limit is reached, the scanner shows an "Too many attacks pending" error message. Once a queued weapon is fired, another can be queued again.
Note that if the Agent's XM reserves are completely depleted by Portal counterattacks, all stacked XMP Burster or Ultra Strikes blasts are cancelled. Agents are advised to consume Power Cubes 
before stacking to avoid this damage-reducing consequence.
