User blog comment:Gershtoot/Blops PC Patch released with interesting sniper tweak/@comment-94.13.187.254-20110423204602/@comment-3123696-20110423211611

TF2 is one example.

With the difference that the bugs and glitches lasted like 2 weeks after release. The other things are tweaks on gameplay and addition of in-game items.
