I just find myself spamming the sniper monkeys with fully automatic rifles and night vision goggles, rings of fire, glue splatters, banana plantations, and spike factories everywhere. It carries me through most maps.
I love games like that. COD Zombies always makes you prepare for maximizing point gains for later rounds. SpiderHeck makes you choose which upgrades you want which will give you a better survival chance. Chess is a great game of planning ahead.
The thing about this game is I pretty much just think in the moment.
