The evolution of the first-person shooter has resulted in the constant re-imagining of a familiar genre. Over the past few years, several developers have taken to throwing in everything but the kitchen sink, with mixed results. On one hand, you have titles like Project: Snowblind, which managed to package a bunch of disparate elements into a cohesive whole. On the other hand, you have Area 51, which tried to add original touches but didn’t nail the basics. And then there’s ÜberSoldier, a budget-priced, single-player FPS that reminds us that the best games are those that perfect the fundamentals. ÜberSoldier is not brimming with revolutionary ideas; there is no gravity gun, no slow-motion abilities, no stealth elements to speak of. Instead, ÜberSoldier equips you with solid weaponry and injects you with pure adrenaline. It’s fast, furious, and an absolute blast, rivaling the action of any quality modern-day shooter.

What keeps ÜberSoldier from being the next Half-Life 2, aside from its lack of multiplayer, is what surrounds the great action, starting with an interesting premise badly presented. Karl Stoltz is a dead Nazi soldier brought back to life as part of the German ÜberSoldier project. These zombified, enhanced ÜberSoldiers are trained to follow the instructions of the one who first issues them a command. When rebels infiltrate the psychiatric hospital in which Karl lives, they recruit him by being the first to give him a command. From there, the plot exists to provide a backdrop—and an explanation for a couple of gimmicky but remarkable gameplay elements. Poor writing and excruciating voice acting round out the flimsy thread that weaves everything together.

Once you grimace your way past the story, though, you’ll encounter surprisingly excellent gunplay with a few twists to freshen the journey. Early on, you’ll discover that when your enemies fall, they may not be dead. They’ll routinely get back on their feet for another potshot if you’re not careful the first time around. On its own, this element may not seem unusual, but when combined with a few others, it changes the way you approach enemy encounters, because mowing your foes down with a spray of bullets isn’t the most effective means of eliminating them. In ÜberSoldier, accuracy isn’t an abstract goal; it provides real rewards.

This brings us to the game’s central gimmick: the energy shield. Karl can activate a shield that traps bullets within a limited radius, including his own. In the early stages, deactivating the shield simply causes the bullets to drop to the ground, but as the shield gains power, it actually flings those bullets back to whence they came. The method of increasing the shield’s intensity is rather clever: earn headshots. Landing three headshots within a limited period of time enhances the shield’s powers, creating a marvelous symbiotic relationship between your shooting abilities and the corresponding reward. When you make a successful headshot, you’ll actually barrel ahead looking for the next two noggins to pump full of lead, gunning for that extra oomph you need in your shield. In turn, your shield flings bullets even further, thrusting you towards your next trifecta.

Increasing your maximum health works similarly, only instead of needing three headshots, you want three knife kills. Thankfully, you slash with your knife using the shift key without having to equip it separately. And while knife action is simple, it too elevates other aspects of ÜberSoldier. For example, if you gun several zombies down at once but do not kill them, you can run up and finish them off with the knife, increasing your max health in addition to spilling blood. They may be gimmicks, but they make for improved warfare.
