Madfinger Games is continuing to tinker with Shadowgun [$4.99] after its shaky late September debut on the App Store. For starters, the game is cheaper. For a limited time, you can grab it at $4.99 instead of its usual upper tier price tag of $7.99. It's also less buggy. An initial patch run has sealed up its iPad 2 crashing issues, the Driller bug in the fourth level, and 'optimized' memory on lower-end devices.

These things combined present an interesting value proposition for anyone who read our review of the original build and remain on the fence. While we loved its technology, we weren't too big on its level design or a handful of its mechanics.

Here's a snippet:

If Madfinger can fix the crashing and save-game deletion issues with a patch, they're still left with a repetitive, but lovely looking shooter. There are hints of true quality in the boss fights and some minor sections of the campaign, but the majority relies on a simple, corridor design that's hard to find engaging for very long.

We've seen Madfinger say that it's continuing to work on the game post-release and that's great news. Its also still planning for an Android release later this month. We've been told that the Android iteration will support anything with a Tegra chip in it, so make sure you've got the right hardware for the job if you want in.
