Tactical thinking? Yes, thanks to the sheer variety and number of enemies on the battlefield at any time. You’ll need to make quick-fire decisions as to what you waste your ammo on. During any one scrap you’re likely to face a horde of ‘charging’ enemies (clockwork rhinos, mutant footballers, three-headed flaming hounds and so on), who are supported by a squadron of flying enemies (choppers, witches on broomsticks, Orc-carrying gyrocopter - the usual) and they’re backed up by some heavy ordnance and weaker ground troops, such as the brilliant Zombie Stockbrokers. Then of course you’ll face an end of chapter boss...
It’s relentless stuff. You quickly realize that as soon as you pick up a large chunk of health, ammo or armor or hit an objective point it’s likely a catalyst for carnage. The weedier guns feel good in your paws and a diverse array of terrain to smash through (nearly everything can be blown up, from trees to pagodas) guarantee you’ll never get bored. Unless you don’t like shooters. Which is wrong.
