Hitman sniper aint free in the uk.!
None of these, but I have noticed it's worth scrolling down to the "Apps on sale" section of Google Play Store now and then - since I disable automatic app updating to review changes to apps already installed, that's an occasion to look at what's on offer. Sometimes I "purchase" an interesting app for sale free, even if not immediately wanted, then save it as an APK, and uninstall it - it's available for future use without clogging the device.
