Use in Research
A study by Barlett, Harris, and Bruey examined how playing Deadly Alliance affected state hostility and heart rate. The manipulated variable was the game's blood setting: Maximum, Medium, Low, or Off. The Maximum and Medium blood levels were found to increase hostility and arousal more than Low or Off. Subjects assigned to the Maximum and Medium conditions also used the weapons-based fighting style more than the other subjects did, which Barlett et al. interpreted as evidence of "more aggressive thoughts activated in semantic memory".
