This is what the Bad Batch wishes it was
In all seriousness, this game is a hidden gem in the world of Star Wars videogames. You take control of Delta Squad, an elite force of clone commandos during the three years of the Clone Wars. Each squad member is functionally the same, but each has their own personallity that keeps the narrative from getting stale.

There are three scenarios total: Geonosis, a hijacked Republic cruiser and Kashyyyk. Each scenario is different enough from the others that the gameplay doesn't feel repetitive. The game is very short, but it does it best with what little time it has. It was developed inbetween movies II and III, so sadly there's no missions on battlefields like Felucia or Mygeeto.

The gameplay is very similar to older shooters like Halo, you pick up weapons and grenades on the way and each of them is more effective against certain types of enemies. You order your squad around to complete tasks or objectives like demolitions, hacking or breaching. When not carrying out a direct order from you they provide support for you and others, so you don't waste time babysitting them. It may be overwhelming at the start but once you get the hang of it you can plan out your offensives with efficiency and coordination.

That said, the game isn't above criticism in some areas. In some sections the game tries to force you to use certain types of weapons, and enforces it by not dropping ammo for others, which just comes out as arbitrary and annoying. Some enemies (looking at you, Super Battle Droids) are bullet sponges even in the lowest difficulties. Some say that the Delta's AI is idiotic; I myself never had much of an issue with it, but there were times I had to go revive a squadmate because they rushed right into a horde of enemies. And finally, the games ends very abruptly after an event which should be emotionally impactful, but it just isn't because the credits roll right after that. It seems they were going to explore it in the sequel, too bad they didn't finish it before the Mouse came.

Overall, its a short but very fun experience, and a good proof of concept for a cancelled sequel. Pick it up only if its on sale.
