Ubisoft has released a new teaser trailer for upcoming title, Far Cry 3, to wet gamers appetites before the gushing waterfall of E3 updates. This entry into the stalking/shooting/stabbing franchise will also include a revamped multiplayer experience that includes a grenade that makes targets go insane. According to PC Gamer Magazine, the grenade will cause all within the blast radius to suddenly lose the ability to differentiate between hostile and friendly targets and begin to accidentally gun down allies. That, my dear geeky friends, sounds like awesome fun. Check out the video below and stay tuned for more awesome updates and geeky amazement here on Just Us Geeks.
