Edit: Review updated as of 17/04/2014 patch.
Guess I can upgrade this to a guarded recommendation. Note that this is not a review of the game itself (see reviews of Strike Suit Zero for a rough idea of how thing shake out), but rather the currently-$3 upgrade to the Director's Cut edition, assuming that you own the original Strike Suit Zero.
There's no doubt that this was a rushed release - a simultaneous PC/XB1/PS4 release was almost certainly too much for a small indie outfit to chew on. Technical issues and missing features, mostly, all adding up to a Director's Cut that ended up being less worthy a purchase than the original release of the game.
The patch released today has addressed several of the key problems. If you've got the hardware to make the game sing, it'll chug along at a solid 60fps with nary a hitch or stutter, and the controls feel all the more responsive for it. You can now also adjust the FOV freely, so if you thought that the game was a little claustrophobic even in third-person mode, you can widen your field of view and see more of the fight at once.
There are still some problems. For some reason, the 'shadows' detail option (one of the supposed major graphical upgrades of this edition) is still greyed out for everyone, and defaults to the 'off' setting to boot. There are also some missing features (mod tools and Steam Workshop support) and content (No integration with Strike Suit Infinity, the survival mode), but those seem to be in the works currently.
Problems as it may have, they've done some good work on the much-maligned campaign of the original Strike Suit Zero here. The story has been rewritten and re-voiced to flow better and generally be more coherent, and the missions themselves have been rejigged to be more exciting (dropping you into spectacular fights sooner) and fairer, with fewer suicidal NPCs to babysit and more checkpoints for if you do fail.
The main value-for-money perk of the Director's Cut is if you hadn't previously bought the Heroes Of The Fleet DLC, which is included as part of the DC upgrade. If you already do have it, then the DC upgrade doesn't seem as exciting a purchase. Hopefully if they do integrate it with Strike Suit Infinity (which I'd love to see with tuned up graphics), it's inherent value would soar.
Either way, it's a bit of a flawed release, but improving. It's a pity that it took so long for the developers to even acknowledge these issues, though, let alone fix them.
