Tactical packages

Tactical packages are gameplay enhancements featured in Halo 4.

Overview
Tactical packages are software updates for the MJOLNIR [GEN2] armor that increase a Spartan's combat readiness and responsiveness. They can be accessed through each loadout either before a match is started or during a player's respawn time.

Trivia
The Resistor tactical package was included as part of the Champions Bundle, released in August 2013. As such, it is not available in Spartan Ops. If a player has it equipped in their loadout, it will automatically revert back to "None". Resistor also does not appear in Halo: The Master Chief Collection.
