Mod packs are groups of mods put into one package for download, often with an auto-installer. A mod pack's purpose is to make it easier for the player to install and manage multiple mods. [73] Mod packs may be created with the purpose of making the original game more accessible to new players or to make the game harder for veterans to enjoy.
The single player campaign in Call of Duty: Black Ops: Declassified consists of objective-based missions that players can revisit to improve their performance. [9] The single player part of the game is actually titled Operations that has the main story of the game with an addition of a Time Trials mode which has the player running and gunning down wooden enemies to beat the time.

Plutonium–gallium alloy (Pu–Ga) is an alloy of plutonium and gallium, used in nuclear weapon pits, the component of a nuclear weapon where the fission chain reaction is started. This alloy was developed during the Manhattan Project .
238 Pu has become the most widely used fuel for RTGs, in the form of plutonium(IV) oxide (PuO 2). [37] However, plutonium(IV) oxide containing a natural abundance of oxygen emits neutrons at the rate of roughly 2.3 × 10 3 n/sec/g of plutonium-238. This emission rate is relatively high compared to the neutron emission rate of plutonium-238 metal.
Weapons-grade plutonium is defined as containing no more than 7% 240 Pu; this is achieved by only exposing 238 U to neutron sources for short periods of time to minimize the 240 Pu produced. Plutonium is classified according to the percentage of the contaminant plutonium-240 that it contains: Supergrade 2–3%; Weapons grade 3–7%; Fuel grade ...
