All item pack unlockables are random. Each pack includes a certain rarity of unlockable items, which are as follows:

The Recruit pack costs 5,000 credits. Every item in the list below can be acquired through the Recruit pack. Once you acquire all Common and Uncommon items, you will begin unlocking Rare and Ultra Rare items.

The Veteran pack costs 20,000 credits. This pack is expensive, but it provides a better chance at unlocking Uncommon and Rare items.

The Spectre pack costs 60,000 credits. This pack is very expensive, but it provides a better chance at unlocking Uncommon, Rare, and Ultra Rare items.

All weapons can be acquired ten times. Acquiring a weapon more than once will increase that weapon's upgrade level. Weapon Mods can also be acquired multiple times, as well as Cobra Missile Capacity, Medi-Gel, Thermal Clips, and other bonuses.
