Operation Thunderbolt picks up where predecessor Operation Wolf left off, featuring not only improved graphics and gameplay but the addition of a second player to the shooting mayhem. The plot is more specific this time, bringing in Hardy Jones to join the original's Roy Adams to rescue American hostages from a hijacked airliner that lands in a fictional African country. The sequel adds pseudo-3D forward-scrolling levels featuring sprite scaling graphics, including scenes where you are inside a moving vehicle, where your submachine gun is somehow more than enough to defend you against fighter jets and their missiles. Hostages are even more of a focus here, forcing you to make split-second firing decisions to avoid friendly fire. All in all, Operation Thunderbolt delivers another simple but enjoyable rail shooting experience from a time before 3D graphics.
