Quake 2 Ground Zero is a second mission pack that has been released for the official game. Created by Rogue Entertainment, developers of Strife (A great game btw) putted much more love and challenge than Xatrix's The Reckoning, 1st mission pack for Quake 2. What do i mean by that? I shall reveal it!
The pack gives you some new weapons such as the powerful ETF Rifle that acts like a Nailgun from Quake 1 with the ability to penetrate the shields or a Tesla Mine which shoots lightning to anyone except you at the very short range with less damage, commonly used to distract or lure the enemy for a better shot. There are also other weapons you can find but i ain't gonna spoil the fun in here other than the fact that this expansion has more new weapons than the previous one.
Like The Reckoning, you have new enemies to deal with, although less than the 1st expansion but it is compensated by their health and their abilities. Such as the sneaky Stalker that attack from unexpected way, DESPICABLE turrets that shoots their chosen ammo such as rockets, blaster or railgun which are extremely smart and more.
Speaking of the smart enemies, Rogue Entertainment has updated the AI for all of the older enemies as well like: Enforcer won't load his chaingun to shoot, Gunners' grenades are more accurate and worst of all, Tanks are even bigger ♥♥♥♥♥♥♥s as they will IMMEDIATELY
shoot rockets at you once you leave the cover which turns them into the most annoying and worst enemy to deal with (Yet ONE new enemy will give you even hard time to kill him than the Tank itself).
As hard as it looks like, the Ground Zero brings more new powerups such as the downgraded Quad Damage which is more common to find called "Double Damage", Defender Sphere which reduces your damage you recieve and attacks the enemy etc. Although the multiplayer lets you use even more new powerups than the single player. Oh and no Invulnerability powerup, as it has been replaced with one of the powerups.
Onverall, this expansion will offer you the biggest challenge of all Quake's mission packs giving you new powerups and weapons to play along with new enemies to deal with. Hope your skill is high....as you will need it.
