I think I remember having something similar though I can't remember it exactly looked like this (very crude drawing) but can't remember the brand or name of the thing and that the colours i had were mostly Yellow, Green and White across all four water guns

They aren’t perfect and probably could have spent some more time on them but these battlemechs are good enough for me given they’re the first things I’ve fully painted in about a decade.

Para Hunter is best Hunter

I will always recommend the old classics of the GM series (GM, GM2, GM3, Origin GM, etc.) and Zaku 2 as they have a fair range of design and general "newness" of the kits
