Well even if it is a nice gun... it is only a gun. Even if it is one of the best gun, i think it is for non skilled player, in order to help them... choose to ruin your early experience by paying or not

This gun is really good, once you get it you won't want to use anything else. It looks exactly like the laser gun, except that this one shoots faster and is much more powerful. It will be available to you when you're told that you will gather alien technology after every mission, so the earliest you can get this gun will be after the mission "The Doctor". Be careful though, it shoots really fast so try to save its ammo for tougher enemies. Highly recommended, and it's so cheap and so helpful that you should get it if you enjoy the game. Maybe during a sale if you're not sure, but either way, you should get it when you buy the main game.

It's a gun. It's not of terrestrial origin, but it packs quite the punch. It's never really mentioned in the game how the hero manages to come across one so early in the game - it just shows up in your inventory one day and nobody seems keen on talking about it. For what it is, it is actually one of the better guns in the game, and having access to it considerably earlier than you would otherwise can be a definite advantage. You'll still need to manage your squad and fight tactically to overcome the alien invasion, so it doesn't turn the game into a complete cakewalk either. It’s a very nice convenience to have, but don't sweat it if you don't bother with it.

I got this DLC ridiculously cheap, and it really makes a difference, besides the gun is very cool, it's extremely powerful, you will gain a big plus when fighting your enemies.Big damage, huge rate of fire. Really nice!

The Light Plasma Pistol DLC for The Bureau: XCOM Declassified adds a new weapon to your arsenal. It's one of these small and cheap DLCs, which are an obvious impulse buy for every gamer who enjoys the game in question. In case of The Bureau, you need to remember that it's not a strategy game anymore but a XCOM shooter, so a good choice of weapons is important. It allows you to choose the right tools for the tasks, to match your gaming style with suitable weapons, and keeps you interested in the game longer. So why shouldn't you get the new gun for what is less than a dollar. Of course you will be able to play with it, but seeing the great model of this weapon and handing it over to your character to give him an edge over his enemies will more than justify the price.
