Take a fairly typical looking real time strategy and then throw in time travel, time travel that affects gameplay in a major way. In this game you can prevent future mistakes, reinforce units in the past and plan the devastation of your enemy, but so can your enemy. How the balance works for this game, I know not, but the prospect that time travel is the major gameplay mechanic, not base building or resource gathering, is really exciting. You have a timeline that shows several minutes and it also shows resources, damage dealt, chronoengery, when you were under attack and units created. In order to manage time travel you have chronoenergy, a regenerating resource that is used to determine how far into the past you can change events, the longer into the past the more chronoenergy you have to use. The game has options like pause and slow motion in order to give the player a chance to issue specific orders in the midst of chaos. Also, there is a fast forward button that is mainly for catching up to the present once you have got into the past. All of this, in basic details, entails what makes Achron stand out against the vast amount of RTSs and indie games. It is made by Hazardous Software and it was released today, 8/29/11, on steam for $29.99, on sale from $34.99.
