You can summon an angelic helper, who'll fight for you for two minutes before dissappearing. It costs a hero point ot do so, though.
You can fire off an amazingly powerful energy blast. So powerful, you have a 50% chance of irradiating yourself when you use it!
Both these powers use the same underlying mechanics - you get a special command against all objects in the level. Using it will produce a customised and potentially very powerful result, but also comes at a costy in the form of a side-effect. These are used to represent powers that you only use in times of desperation.
