I of the Enemy: Ril'Cerat is a totally free, stand alone, science fiction real-time starategy game, that is the first chapter in the "I of the Enemy" saga. The player is a Lokob (luh-kobe) officer who is in charge of his race's contingent. Major Verkkal (voice talents of Ian McNeice, famed for his role as Baron Harkonnen in Dune) is his trusted friend and Field Commander. Emphasis in this game has moved away from gathering, mining and building, and instead concentrates on interesting tactical problems.

Realistic facets of combat include reinforcements arriving according to an Order-of-Battle (which may be misleading due to poor intelligence), via a temporal gate. Indirect fire weapons (artillery) targeted by spotter units discourage fixed defenses. Each unit visibly changes as it advances in experience, toughness and morale rating, and can be carried forward to the next exciting missions as a trusted member of your team. "Advanced" units acquire heavier weapons or equivalent combat advantages.

Success in battle is achieved through maneuver rather than larger quantities of units. This makes it more important for players to achieve favorable match-ups, rather than just waiting for overwhelming numerical superiority.

Scorched 3D is a game based loosely on the classic DOS game Scorched Earth "The Mother Of All Games". Scorched 3D adds amongst other new features a 3D island environment and LAN and internet play. Scorched 3D is totally free and is available for both Microsoft Windows and Unix (Linux, Mac OS X, Solaris etc.) operating systems. You can pick up the game and begin playing very quickly. Then, when/if you are interested, you can poke in the dimmer recesses of the game and get into the strategy (or just ignore it altogether!). At its lowest level, Scorched 3D is just an artillery game with two+ tanks taking turns to destroy opponents in an arena. Choose the angle, direction and power of each shot, launch your weapon, and try to blow up other tanks. That's basically it. But Scorched 3D can be a lot more complex than that, if you want it to be. You can earn money from successful battles and use it to invest in additional weapons and accessories. You can play with up to twenty four other players at a time, mixing computer players with humans. There's a variety of changing environmental conditions and terrains to be dealt with. After the end of each round (which ends when everybody dies or there's only one person left), you get to buy stuff using the prize money you won from previous matches.
