In upcoming Heroes of Resistance there will be some new cards. One of them, I guess, is called Proton Throttle.
3 guesses I have are:
Can fire a torpedo backwards - no firearc needed and act as a proxyimity mine.
Fire normal and gives out splash damage. In other words, hits and crits in range 1.
Perform a boost. Before moving - roll dice and see damage on the defender at range 1.
