Umbrella Corps' single player isn't convincing and, what is worse, its multiplayer is confusing and chaotic, mostly because of its clunky mechanics and horrible performance. Also, the lack of content makes it repetitive in the short term.

It doesn’t feel like it’s finished, and even if it were to be further refined, it would just be a low-budget Gears of War-style shoot-‘em-up. There’s no reason to play it.
