It is a great guide but bear in mind that melee is something you mainly only do when winning in Star Trek Online. First, use your mini map. You have a map. It is mini. It shows you where your teammates are. You should try to find them. Finding your teammates takes priority over finding enemies unless you are winning by a lot. You should pay close attention to this as just because your teammates were following you a couple seconds ago doesn't mean they still are.
Second, get a split beam rifle. Disclaimer: Weapon (star trek credits) balance is changing in Update 1.
What weapon are you using right now? Unless you said, Split Beam Rifle, throw it into the dumpster. Get a split beam rifle. If you're tactical with a lot of ground combat training get two. The sniper rifle is superior in a 1evel (star trek online credits) 1 fight. Are you fighting 1evel 1? No, because you heeded the advice and met up with your teammates, as did your opponent. So get a split beam as your exploit weapon.
For your second weapon you might want a good expose weapon. Personally suggest a stun pistol or a full auto weapon. The other pistols do not have enough range to do what you need them to do and the cylinder AE weapons do not hit enough targets. The advice is to get a good long range cone AE expose weapon to go with your good long range cone exploit weapon. Or, as mentioned, just get two good exploit weapons, especially if you are Tactical or if you have a lot of kit-related expose abilities and therefore don't really need an expose gun.
