So im still thinking should I buy this or not.
Is there some list of important stuff how this game works.
Like unlocks, do you have to unlock better weapons with 1000h playtime?
How are the hitboxes etc?
Is it mostly pilot vs pilot and rare times some mech action or 50-50?
I haven't played R2 yet, but I played R1 almost every day for 6 months from when it came out and I've played the Tech Test for R2 for a few hours.
Unlocking all weapons usually took about 15-20 hours of gametime in R1. In R2 you get credits/merits so you can unlock what you want. When you prestige, apparently what you unlock that way stays forever. It's really not a big deal.
Hitboxes are... I mean I think it's fairly standard, but then I don't play CoD so I don't know what this is referring to. A few weapons are AoE though.
Depends on your playstyle, in a regular game (that isn't Pilots only mode) I'd say you can make 60-80% of your time be in a Titan providing that you're correctly building them. You get them as a reward over time or by doing damage, stealing batteries etc. so in the Tech Test I would stay in my first Titan until I lost then get another one within the minute.
Here is Alpha Tech Test gameplay if you want to judge how long you can stay in one (watch from):

In R1 you could nuclear eject and kill enemies from your dead Titan, and immediately get another one.
Oh that was for the achievement too? I thought that was just for the regeneration thing.
Only the Plasma Railgun* iirc
