Good lord! There are plenty of these 'small country-causing-loadsa-aggro' games around, aren't there viewers? Another Operation Wolf/Thunderbolt 'shoot-anything-that-moves' game is here on re-release - it's Cabal.
You are volunteered to enter enemy territory with nowt but a machine gun, a handful of grenades and a large amount of guts (or, if you prefer, stupidity) to battle through the 20 single screens that make up the game.
You begin each section with a view of your character looking up the screen. There are buildings and walls, from behind which the enemy forces leap to spray the area with lead.
The most sensible thing is to return fire, and this is indeed what you can do (with great effect). Firstl, with your machine gun, then with the really big and powerful weapon pick-ups that are at your disposal.
Originally released at the same time as Op Thunderbolt and sadly overshadowed, Cabal isn't quite as slick as Thunderbolt, but it's just as playable. But then, I love a good shoot-'em-up: the more violent it is the better! Cabal certainly delivers the goods.
