Feature
In order to stand out from the competition, the developers of Operation 7 created a weapon assemble system which enables players to assemble and modify weapons. Players can replace barrel, butt, bolt and other components freely. And each component can use protective coloring. Each gun will vary in range and accuracy depending on the material is used. In addition, players' body movements while shooting, such as dashing or holding breath, will also influence destruction and accuracy.
Real life maps are another feature of Operation 7. Shooting games either use famous battlefields or virtual scenes as their maps. But Operation 7 uses real life locations as its maps, for example Japan's Shibuya will appear in the game. And each map can be played on the day or at the night.

To achieve gorgeous and diversified sound effects, more than 700 types of sound into Operation 7. Each character has seven decorative item slots in his inventory. He can change costume, helmet, goggle, etc. In addition, the character can wear camouflage coat to improve his disguising ability.


Let¡¯s start
During the character creation offers operation 7 25 uniforms and clothes in each with 3 different colors. You have nearly 100 possibilities of arranging their character after your fancy.

After character creation, you¡¯ll be put through a brief mandatory tutorial. The final leg of the tutorial contains a short training obstacle course which puts to test the gameplay basics introduced earlier in the tutorial; aiming, firing, reloading, using grenades, running, ducking and so on.
Back to Basics
After the tutorial, you¡¯ll find yourself in the game lobby with a list of rooms hosted by other players. Operation 7 has three game modes; Head Hunting, Death Match, and Survival. While all three modes are team based, the most common mode is Death Match where two teams battle it out for the most kills. Survival is last man standing and in Head Hunting, players defend their team general while hunting down the opposing team¡¯s general. Rooms support up to 24 players, though this varies by game mode selected. The host may also tweak such settings as game time, friendly fire and number of kills required for victory. 
What is the Difference?
On first view one could mean that is to be seen no differences to other FPS games. Operation 7 emphasizes modern day combat so expect to go in to battle with the usual suspects; AK-47s, M4s, MP5s and so forth. After further play though, some key differences do emerge. Operation7 support Scope Mode, Dot Sight Mode, and also Gun Sight Mode. You can also tilt to the side in order to shoot stealthily behind object. You should control your own sound. Try to hide yourself or move quickly away from opponents by hiding the sound of your breath and other environmental sound effects.
Operation 7 is a MMOFPS, which puts much worth on realism. The main feature of Operation 7 is a really gigantic weapon management. You can create your own Weapons. Each weapon is compound from 6 parts, which are selected before. A part has effect on the other one. For example you can convert your M16 rifle to a sniper gun. But that is not yet everything. Because a weapon consists of 6 parts, must be not bought complete rifles. You can buy individual parts separately and assemble to a weapon!!
The weapons, which you bought, does not purge. I.e. player, who plays not regularly Operation 7, does not have to be afraid that this his weapons after some time purges. The weapons arises more tactical possibilities in fights.
Operation 7 is so realistic that the weapon becomes defective during the fight, if you do not repair your weapons. Who does not care for your weapons, the weapon can fail in important moment.

One Shot, One Kill
Operation 7¡¯s catch phrase is ¡®It only takes one shot! One who aims first, kills first!¡¯ and for the most part this is true. In any map with open areas, it¡¯s vital to aim and fire from a distance since it is nearly impossible to survive long enough to get into close combat. This definitely gives the game a more realistic feel over its rivals. And if two player come into close combat, there are possibilities, to punch or to throw the knife or to knife the enemy.
The ammunition have depending on size different impact power. For example 5.56mm ammunition raises damage of 65 points, 5.45mm 67 points and 7.62mm 80 points etc. In Operation 7 there is condition points. Condition points have effect on run speed and jump strength.
