Helpful tip for humans: if you ever find yourself in inclement weather, such as the rare steel storm that only comes out at night, seek shelter in the nearest building. If you can, find the Temple of Leemeealown, as it offers the best protection from these dangerous conditions.
Steel Storm (Mac/Win/Linux, 258-310MB, free) - A surprisingly robust top-down action game that puts you in control of a mech armed to the teeth with weapons. Blast through destructible environments as you carry out tasks ranging from making it to the exit alive to laying waste to half of everything you see. Very action-packed, yet you always feel in control of your mech and of your fate. The controls are extremely responsive, the levels and missions are interesting, and the game's level of polish is very high. Episode One is free and contains a number of missions along with multiplayer, campaign and deathmatch, and a level editor. Episode Two is in the works as well, and it looks like it's going to be even bigger and better than this one!
Rocky Memphis and the Temple of Ophuxoff (Mac/Win, 6-7MB, free) - Treasures? You want treasures? Well, go get you some treasures, then. C64-style! Guide Rocky through over 600 trap-filled rooms, each stuffed with tons of loot to pick up. Gather everything, then return to your vehicle to see how quickly you worked. Your only ability is the power to jump, so you're mostly helpless against enemies. Some potions, however, grant you temporary powers, such as super speed or an uncanny magnetism to certain pieces of pretty. A great retro-styled game that's fun, even if you're terrible at it!
They Come Out at Night (Windows, 1.4MB, free) - True to its name, They Come Out at Night is a top-down survival shooter where you collect ammo and weapons during the day and barricade yourself in by night from the baddies that appear. A timer counts how much daylight is left, and when the darkness arrives, so do the waves of little critters. You've got plenty of weapons to deal with the foes as well as the ability to move certain blocks with your mouse, but their sheer numbers make it tough to do without some sort of a strategy. The game was made in seven days and, according to the creator, is technically unfinished, but it's still fun to play "hide and don't die".
