A term used in MMORPG's in multiple forms.

v: To provoke a mob (enemy or hostile NPC) to attack you by entering its aggro range. The aggro range (or radius) is the zone around the mob which, if entered, will cause it to attack without provocation.

n: Used to describe the attention of a mob, or its current target. In group fights, the Tank is supposed to "hold aggro" by keeping the mobs focused on him. To "have aggro" is to currently be the target of a hostile mob. Aggro is also sometimes used interchangeably with the term Threat when referring to the DPS.

The P90 (Project 90) is a SMG, part of the PDW (Personel Defense Weapon). It uses 5.7x28mm round, which looks like a scaled down 5.56 NATO round. There are a lot of discusions about the efficiency of this ammo, because of it's size. But still it can pierce through any type of military vest, at the range of 100-200m. It's ergonomic and can be used by both left and right hand. It uses a bullpup layout, so it's compact, and it's quite light - about 2,2kg. The results show it's quite acurate too.
The P90 has an interesting design, and ejects the spent cases in the back of the weapon. It uses quite an interesting and big magazine, which in the end aligns the round with the reciever.

The eighty eight was a weapon in the German army in World War Two. Actually an anti-aircraft weapon firing an 88 mm shell, the 88 had a major advantage in range over many Allied artillery pieces. German gun crews fighting in the Spanish Civil war turned the gun on approaching tanks that had broken through their lines - unsure how effective they would be. Germans quickly converted the gun to anti-tank use, putting the gun into their vaunted Tiger Tanks. Allied tanks were knocked out before they were able to get close enough to use their weapons. The eighty eight had a self ejecting shell and were deployed in numerous configurations including tanks, self propelled guns, and a four legged gun that was towed behind a vehicle. They were less effective at close range.
