Actually, the weird arms on the zombies (weapons?) were a bit wacky. Then I noticed the chainsaw, and thought “wacky zombies and a chainsaw” and since SadleyBradley had already guessed a Dead Rising, it’s the only game I could think of that might fit. I’ve never actually played it. Nearly bought it once. Still might some day.
Anyhow, onto the next one! And, apologies up front if this is a little low quality. Got it from a youtube video.
