The game features an undocumented "Dynamic signboard" system -- if the wrestler you select shifts from "good guy" to "bad guy" alignment, the signs that appear in the audience will adopt a negative tone towards the wrestler. Two positive, two negative, and two neutral signboards exist for all of the game's superstars.
When the "Set trap" command is selected, one out of every one hundred times an anvil will hit the enemy wrestler, putting him or her permanently out of commission. This was designed to be so rare that anyone who reported it happening would be labeled a liar.
The entire development team was laid off on the day the game was mastered for US release. Add
