You become visible at a certain distance, depending on you the +Stealth rating your MES gives you. I've snuck up to < 3KM of people with MES II.

ah what like the feddybears (i.e you) batlle cloak thats an IWIN button .
you want cloak do a kling other than that shut yer pie hole.
stupid bloody fed ****s need a good kick in the stones.

Now, now. Don't take the bait.

id like to see more items that can be used in general.... such a potential goodness being wasted on batterys and red matter. (and them shuttles i missed out on)

The only ship that has battle cloak is the Bird of prey.
and carriers don't get a cloak.
As someone on both sides I would not like a battle cloak to be a device you can just slap on any ship.
the Klingons pay a heavy price to have a battle cloak and ships that cloak. that would be unbalancing to the Klingons . They have weaker hulls and shields to have those cloaks

Wow, how un-Star Trek of you.

As a Fed who hopes to one-day team up with Klingons to ride the Alpha Quadrant of Borg I salute you for your honorable response to this post.

Translation: You totally ROCK!!!

Yes I know, But it may be a fun idea to play around with. Obviously it isn't a battle cloak, but it can be used in combat like a battle cloak. The klingons could use it too so I'm not sure it would seriously affect game balance. And it isn't a cloak you can just slap on, it's a single use device with a limited duration like a battery plus i have said it would have to be less effective for it to play fair. Like loose the decloak bonuses.

I used to play a klingon aswell and I think one of these on a carrier would be an interesting thing to mess with.

you want a less effective cloak put MES 2 on your ship. there now you have a cloak that has no cloaking bonus and is less effective. you want it to be more cloak like boot your aux power setting to 100 now you have your very own cloak. see problem solved

As a Borg I take great offence to this post.
