little help om a game Armored core 2 thanks

[Death Dragon]

A few things really assistance on any or all would be appreciated.

1st off does anyone know a mission order where you can play through all the missions. I keep having to load the game and find the ones i did not get a chance to beat. Same thing with matthas in the arena is it possible to fight him before you already beat the game

2nd the thing that is really driving me nuts. I beat the game normal & hard when i beat it & reloaded my game

storie 33 ARENA 55 WINS achievement 77%

beat Riot & Matthas & the missions i missed

Sortie 36 arena 57 achievement was like 89 %

went back gathering missed parts parts found in total are as fallows:

1. radar - AC test
2. FCS - Guard secret
3. extension - Escort Train
4. Back unit - Infiltrate Radar base
4. Booster - Destroy radar base
6. Optional part - Destroy containers
7. Saber - Rescue research team
8. Energy rifle - Stop surface weapon
9. Shield - Underground Railway
10 Head part - Ground-based attack
11. Back unit - Zio city suppression
12. Generator - Eliminate Leos Klein

sortie 41 arena 57 achievement 98%

now all the missions on the stage select say complete all the arena people say win

am i missing a part if so what mission is it on because unless its somewhere way up Klein's but i cannot find it if its not a part could someone tell me what this mysterious 2% may consist of. To know i have stomped this game several times & still missing something is rather annoying

one other thing i would not mind would be a way to get that rifle earlier if anybody knows one.


Thank you for you time
