*Call of Duty: Black Ops requires an initial hard drive space of approximately 24GB to download and install the game via digital download (8GB of compressed files, 8GB of decompressed files and 8GB of installed files).
It's important to mention that while Black Ops 1 is still playable in 2024, the player population may have decreased compared to its prime years after release. This means that finding multiplayer matches might take longer or result in fewer opponents.
A major strength of the Soviet economy was its enormous supply of oil and gas, which became much more valuable as exports after the world price of oil skyrocketed in the 1970s. As Daniel Yergin notes, the Soviet economy in its final decades was "heavily dependent on vast natural resources oil and gas in particular".
The decline of the Soviet economy is sometimes explained by exoge- nous shocks, like the troubles in the oil industry, the coal strike in the first quarter of 1990, the collapse of trade with Eastern Europe following its liberation, the plant shutdowns for environmental reasons, and the regional frictions in the USSR.
