Armored Core 4: For Answer

• The Altair is king as one of the best guns you can have on your mech, fast and accurate and pretty good for general fire and come as standard on one of the starter mechs. Blades can now do a whole lot more damage, so having a really fast light mech with two blades on it can mulch many opponents quickly.

• One of the best things you can do early on is to pump through as much of the arena as possible, it'll get you a bunch of weapon and part unlocks.

• I can't remember exactly but I'm pretty sure you sell parts for the same price you buy them at. You might want to test that rather than take my word for it, but I do remember realising that you could basically just experiment to your hearts content and never force yourself into crappy leftover parts.
