Epic har ikke glemt deres seneste darling, Gears of War 2, og derfor er der endnu en Update på vej. For at være mere præcis: Den fjerde i rækken! Denne gang er det dog ikke de helt store bug- og glitchfixes, men lidt småting omkring XP og så en masse om Achievements til det kommende DLC.

Den største ændring bliver at det med TU4 bliver muligt at grinde XP i Horde mode, og du derfor ikke behøver bevæge dig ind i det farlige multiplayer, hvis du ønsker din magiske level 100 rank. XP'en bliver givet for hver gennemførte wave, og de takseres således:

o 50 points per completed Casual wave.
o 75 points per completed Normal wave.
o 100 points per completed Hardcore wave.
o 125 points per completed Insane wave.

Sagt med andre ord: Du skal klare 54607 waves på Insane, hvis du ønsker at gå fra level 1 til level 100 ved blot at spille Horde. God fornøjelse!

Det er dog ikke kun ligegyldig XP for Hordemode der kommer med TU4, hvor de achivement-interesserede (læs: whores) kan glæde sig over hele 325 fordelt over 13 achivements:

o "My Way or the Highway" (25 points): Without being detected, complete the "Road to Ruin" deleted scene after choosing the stealth option.
o "Highway to Hell" (25 points): Complete the "Road to Ruin" deleted scene after choosing the guns-blazing option.
o "Two for the Road" (25 points): Complete the "Road to Ruin" deleted scene in co-op as either Marcus or Dom.
o "Be Careful What You Wish For" (10 points): Reach level 5 in multiplayer and complete waves 1 through 10 on the War Machine map in Horde (any difficulty).
o "Ride It All Night Long" (10 points): Reach level 10 in multiplayer and complete waves 1 through 10 on the Highway map in Horde (any difficulty).
