Tomb Raider: Legend

Story related and cannot be missed

This trophy will unlock as soon as you complete level 5 (Kazakhstan), refer to the spoiler for more info on this level. This level has a boss fight.   This level is easyish, you start by fighting the enemies at the base and there aren't many of them. Once you do all the objectives here you have another motorbike sequence, you are faced with enemies and you have to keep up with the train. Once in the frozen labs you must avoid the green gas as it's pretty dangerous. Once you have done everything there's a boss fight with Amanda and that unknown Entity thing. You have to push the orbs above you then pull them towards you to link the circuit, then the piece of the sword becomes grab-able, you need to grapple it then pull it down. For more help see the speedrun video on the Good Time in Level 5 trophy as it's hard to explain in text form. Once you defeat the Unknown Entity. The level will finish once you defeat the boss.
