The gaming website 'PlayDevil' has posted a review of the XBLA title "Rocket Riot".
Here's a snip:
"RR is a classic dual-joystick shooter. You move with the left stick (controlling your arse-pack) and shoot with the right stick. However, RR has a slight twist on this basic mechanic by adding a rudimentary physics engine into the mix. So you need to pull back on the stick to build up power, then aim whilst trying to allow for the fact that your shots will arc before falling away. This adds a bit more skill into the mix than with games such as 'Geo Wars'."
