	If the mission is against a crashed UFO, all [[UFO_Power_Source\|UPSs]] present in the craft have a 75% chance to explode (assuming the detonation of another UPS doesn't destroy them first). This is performed during a hidden "first turn" (actual ~~gameplay~~ always begins at turn 2).

This is performed during a hidden "first turn" (actual game play always begins at turn 2).

	Because UPS explosions tend to have very high damage ratings (above any other tactical weapon in the game), they tend to obliterate anything nearby. This always results in the [[Elerium-115]] that was placed in them being destroyed, often causes massive damage to the insides of the UFO, and usually kills any aliens unfortunate enough to be in the blast's path.		Because [[Explosions#UFO_Power_Sources\|UPS explosions]] tend to have very high damage ratings (above any other tactical weapon in the game), they tend to obliterate anything nearby. This always results in the [[Elerium-115]] that was placed in them being destroyed, often causes massive damage to the insides of the UFO, and usually kills any aliens unfortunate enough to be in the blast's path.

	For some reason though, the game will often have aliens still alive within a medium scout, despite an almost point blank proximity to the blast. Furthermore, these aliens will either be at full health, or dead. Maximum health and species of alien do not matter, the game merely gives nearby aliens a % chance to die or escape unharmed. This check is only performed on aliens which were determined to be within the blast affects. The blast does NOT DO DAMAGE to aliens. It either kills them, or leaves them unharmed. As proof, on Superhuman difficulty, it is pretty common to see Mutons survive a Blaster Bomb impact, albeit with major damage. However, you will NEVER see a damaged Muton upon beginning a UFO Recovery mission... they start either at full health, or dead, nothing in between. In addition ~~sectoids~~ and Mutons have ~~similiar~~ survival probabilities. In conclusion, it is clear that the UPS explosion is NOT treated the same as a normal explosion...

	In addition, due to limitations of the game engine(as well as to challenge the player), the aliens will always have at least one or two units left alive. The number of surviving aliens also appears to be randomly determined.		In addition, due to limitations of the game engine (as well as to challenge the player), the aliens will always have at ''least'' one or two units left alive. The number of surviving aliens also appears to be randomly determined.

	The UPS ~~explosion is also the only explosion in the game~~ to ~~create random~~ terrain ~~damage. Taking a medium scout as an example, sometimes it will blow off the roof of~~ the ~~UFO. Sometimes it will destroy multiple outer walls. Whereas normal explosives will give the exact same blast pattern, every single time~~.		The UPS explosions go off with variable force, as opposed to conventional blasts which never vary. They propagate and deal damage to terrain in the usual manner.

	The check to see whether the craft crashed or not is determined by the relevant [[LOC.DAT]] record (as defined by [[MISSION.DAT]]). The amount of damage done to the craft has no effect on the amount of power supplies that will explode, nor how much damage they'll do.
