A hot fix is automatically applied at the "Press Start" screen when Aliens: Colonial Marines is connected to the internet. In general, hot fixes are used to temporarily address issues between major updates. Hot fixes are not permanent -- they are temporarily stored in memory during the game session and lost upon exiting Aliens: Colonial Marines. To ensure that you receive hot fixes, make sure that your system is connected to the internet when Aliens: Colonial Marines boots up.
An update contains changes that are permanently stored on your system and only needs to be downloaded once. You can download the latest update by launching Aliens: Colonial Marines while connected to Xbox LIVE. You will be prompted to install the update if you do not already have the latest version. All updates are cumulative; you only need to install the most recent version to receive all updates.
