Obvious stuff, I know, but there are plenty of players out there who don't yet know this. 1.) Once a base is hacked, no enemy players can spawn there and terminals cannot be used. So get the hack in quick. And once the timer is ticking, make sure it stays ticking and defend the command console. 2.) Only those bases linked to by one of your bases (via the lattice) can be hacked, UNLESS the base is drained of power and has turned green (NOT the same thing as the generator being destroyed). 3.) The only reason to destroy a gen is to stop the enemy using their terms/respawning. Its a valid tactic to do when you are trying to do the hack, but once the hack is done there is no point in killing the gen. Let's state that last one again, as an awful lot of people don't understand this: You're doing NO GOOD AT ALL shooting up the generator once the hack has started. If you don't know whether the hack has started and don't want to ask, check the map - a little flag in the centre of a base shows that it is under hack (and the colour of the flag tells you which empire is doing the hacking).
