Being an RPG/run and gun hybrid influences this game in interesting ways. The leveling up system isn't actually that prevalent, mainly low increases in stats and unlocking items in a way that could easily just be done by unlocking items based on what level you've completed. The amount of variety of weapons leads to different builds on the other hand, which feels more RPG influenced. A lot of times, taking damage feels inevitable too like an RPG, where the practical solution is using healing items rather than learning to dodge better. This feeling of inevitable damage actually kinda fits the mecha feeling to me, your mecha is big and weighty, there as places you can only walk through on foot, the dash is somewhat of a commitment too, so a big weighty mech inevitably taking a bit of damage that needs repairs feels fitting.
Much of the plot isn't really that interesting, being relatively standard conspiracy stuff, but Genoce is a pretty nice antagonist despite that.
