Whilst being designed for use with Starbright's Mecha Clash game, the Harasser mecha is worth a look if you are playing any game that includes mecha.
The real delight here is the copious background provided about the Harasser's development and operation. This will be of particular use if your game centres around mecha pilots rather than the actual brawling that takes place when they are operating their mecha, although that too is supported by this product (you might have to do some stats-wrangling if you are not playing Mecha Clash, though!).
The illustrations are good, too, with several views from different angles of the Harasser, including labelled ones showing the important parts. If you want to introduce this mecha into a skirmish with other forces, there are two rather useful battle-maps - one showing a fallen Harasser and one with a top-down view that could be used if someone tries to climb on the mecha's shoulders. This could be during an attack in an attempt to get at the pilot or troops being carried into battle (or away to safety) on its shoulders... even if this is not recommended due to the lack of hand-holds!
You also get some star maps and notes on the setting of Mecha Clash, adequate but not very clear.
But it is the contextual notes that make this a real gem.
