All Zombies Must Die could have been a much better game. The level-building RPG elements as well as the weapon-crafting add some much-needed depth to a genre that is usually shoot first, but never ask questions. However, the constant backtracking, repetitive quests and lack of real variety dulls away whatever fun you'll be experiencing. The bad humor and lack of online multiplayer don't help things, either. With so many other zombie-themed twin-stick shooters on the market, it would be best to save this one for future gaming dry spells you have with local friends.
