The game features a career mode with car purchases and upgrades; third-place finishes in each cup (a series of races on specific tracks) is required to unlock the next set. The FlatOut mode includes a mix of non-traditional game modes, and quick play and multiplayer modes are also available. In addition to traditional races, FlatOut 4 features assault races (with powerups), carnage races (where you score is based on damage caused), a variety of physics-based stunts (including long jump, high jump, golf, and curling), and destruction derby arena modes (including capture the flag). Causing destruction will award nitro, which can be used for quick bursts of acceleration. It is sometimes difficult to tell what is considered a “solid” object and what is not (Telephone poles? Destructible. Trees? Not). The handling is a bit loose, and there is occasionally questionable physics when hitting objects, causing spins that result in poor finishes. The AI is good enough for an arcade racer, piloting through each track appropriately and being aggressive with human drivers and other AIs. While not approaching the high mark set by FlatOut 2, FlatOut 4 is certainly a competent arcade racer and successfully eliminates the odorous smell left by FlatOut 3.
