When you read the description about Jack’s Repulsor ‘The wall must be in front of the monster to stop it’s movement. If the beam is red, it’s not working!’
Well the ‘red beam’ was in Legacy Evolve as his repulsor beam would be red when it wasn’t stopping the monster. However in this current version (Stage 2) when the beam doesn’t work it glows a grey color and not red. I think that the wording should be fixed/changed as some players may lookout for a red beam when in actuality it’s grey.
