Mutantleg's retro-styled shooter Lab, with music by Arteria 3D, isn't all Doom and gloom!... except for maybe that first part. There's definitely a lot of Doom in this homage to old-school action, and hey, sometimes you need to blast your way through halls of mutants. Use [WASD] or the [arrow] keys to move (hold [shift] or [X] if you want to side-step while moving instead of turning), and [Z] or [ctrl] to shoot. Don't get too trigger-happy since you have limited menu, and of course you'll want to dodge enemy attacks and keep an eye on your health. As you might expect, you'll find various pick-ups, like armor, laying around, some of which are hidden inside boxes that need to be blasted open. Just shoot your way through gob-spitting mutants, giant flying bugs, hopping... thingies... and more, keeping an eye out for secrets, of course. Some may find Lab's dedication to being such a faithful homage makes it a little too simple and familiar, though it gets more elaborate after the training-wheels first stage, but if you want some good old fashioned shooting like grandma used to make, Lab is an easy bet.
