Pulse Tank
In Beast Mode, Pulse Tanks fire huge explosives. They go into Beast Mode for 12 seconds when a friendly unit dies.
General Information
Pulse Cores are used to upgrade and build the Pulse Tanks. They can be acquired from a mission and Zoot's Loot or purchase them at Shop for 25 Platniums each. Pulse Cores cannot be recovered from destroyed Pulse Tanks. It is best to withdraw the Tanks from a battle earlier if they are overwhelmed by enemy base's defensive towers. Pulse Tanks are very useful when it comes to destroying Tesla Towers since the range of the Tesla Tower isn't wide enough to attack the Pulse Tank which can attack the Tesla Tower from a long range.
Strategy
Because they have a great range and explosive power (in Beast Mode), they are best used to attack short ranged towers and to quickly destroy/collect any nearby reasources.
Also, it is best to use a Pyro as bait so the Pulse Tanks can enter Beast Mode; but only if the Pyro can survive long enough to do some damage, otherwise a Marine makes for cheaper bait.
Note: There are several high level Faction bases where resources can be aquired easily wiith Pulse Tanks, or a Pulse Tank, without taking a single hit, or losing any units. There may also be high level Players in your sector who have bases with equally accessible resources, or buildings that can be destroyed for quick XP; however be careful not to start any undesirable feuds.
