Ingress XMP Burster

An XMP Burster in the game Ingress is a primary area-of-effect weapon used to attack enemy portals by damaging their resonators and destroying mods, with higher-level XMPs dealing more damage and having greater range, requiring players to manage XM energy and time their shots for maximum effect. 
How They Work
    •    Damage: XMPs reduce the energy (XM) of resonators. Closer resonators take more damage, and mods have a chance to break, especially with critical hits.
    •    Levels (L1-L8): They come in 8 levels, with higher levels costing more XM but doing significantly more damage and having a greater range
    •    Charging: Holding the fire button charges the XMP, adding up to 20% bonus damage if released when the targeting ring shrinks perfectly
    •    Mitigation: Portal mods (like shields) reduce damage, but every attack deals at least 1 XM of damage, notes the Ingress Wiki.
    •    Stacking: You can queue multiple XMPs to fire in quick succession, though portal counterattacks can deplete your XM and cancel queued attacks, so players use Power Cubes for energy. 
Strategic Uses
    •    Destroying Portals: The main use is to take down enemy portals.
    •    "Pinging" Portals: Low-level XMPs can be used to ping portals for location updates or to annoy opponents without significant risk
    •    Mod Removal: Critical hits can destroy mods, making it easier to capture portals
