Parkan II & You Are Empty
Parkan II is a free-form space game in the vein of Elite or Privateer. The player is owner and commander of a ship roughly the size of a modern navy destroyer (though it's dubbed a corvette), which of course can be upgraded. The player can buy robot tanks and robot guards for the ship. The tanks are used on planetary invasions, which consist of taking over two facilities. While on planet, the full size of the user's ship is revealed, and it's quite an impressive craft.
Combat is rather similar to most space combat games, resembling duels between space fighters more than battleship slug fests. The interior of the player's ship is fully navigable and actually part of the gameplay, which is where the robot guards come in. The on-ship and on-planet expeditions have the lead character running around in a suit of powered armor, either fending off attackers or seizing control of an enemy facility. The suit is upgradeable, like the ship. The galaxy is huge, with over 500 star systems, with several planets per system on occasion.
You Are Empty
You Are Empty is a strange title for a first-person shooter, but apparently in the original Russian it makes sense. In English, it requires a bit more explanation; the implication being that 'You Are Empty' means you have no ammunition and are in deep shit.
You Are Empty is a first-person shooter with a rather attractive game engine that the presentation team likened to Half-Life 2. The comparison is actually somewhat apt in the graphics department, though the gameplay seems quite different. You Are Empty feels like almost a survival horror game, but with more action than mere running away.
Whirlwind of Vietnam
Whirlwind of Vietnam tries to do something few simulations attempt - helicopters. The game obviously focuses on the Vietnam war and puts the player in the cockpit of a Huey or Cobra, in a realistic fire support simulation.
The player flies sorties with his air cavalry comrades, providing close air support while men are being dropped off in their landing zone. The helicopters themselves are done in full 3D, complete with detailed cockpits and working gauges. The player has the option of piloting the vehicle itself or switching to a co-pilot or gunner position. Since the game engine is based off Il-2 Sturmovik's, presumably there will be a myriad of realism options on top of all that as well.
