i bought the MGS for PSX on my psp and i cant kill Liquid when he gets into Metal Gear Rex!!! he makes me mad!!!! can anybody give me any tis on how to kill Rex? (oh i know how to kill him the first time but when liquid pops out of the head i cant kill him!!! he is so going on my Death Note xD)
Umm try this guide hop its help.... Fighting and destroying REX isn't particularly difficult. A chaff grenade here and there scrambles its VR-based targeting interface, then destruction of the radar dish mounted on hisright side will permanently destroy this radar-based VR interface. After which, the mouth portion opens up and you must destroy the control center to completely ensure REX's death
Like he said, use chaff grenades then attack using that Rocket Launcher, you need to evade his attacks first.
