Halo: Combat Evolved Trial

Halo: Combat Evolved Trial is the demo version for Halo: Combat Evolved, for both PC and Mac.

Campaign
Only the Silent Cartographer mission can be played in the Halo Trial. Similar to Halo: Combat Evolved, the level features similar environment, weapons and enemies. However, players would not be able to save the level, as doing so will restart the level.

Multiplayer
Blood Gulch is the only map featured in the game with the capability of hosting up to sixteen players per game. In contrast to Halo: Combat Evolved, Halo Trial's version retains similar weapons and vehicles but features low graphics settings, as players are encouraged to buy the full version. There are only two gametypes: CTF Classic (First to 3 Flag Captures) and Free-For-All Slayer (First to 25 Kills).

Trivia

 * When the player closes the demo, an tongue-in-cheek advertisement for the full Halo PC appears, which features Sergeant Johnson telling (almost ordering) the player to buy a copy of the full version (Showing scenes of combat with cartoony music). However, one can simply bypass the advertisement by pressing  or   and ending the program, or by using the   command line parameter on a windows. On a Mac, the player can just press Escape or Enter. The video can also be removed by deleting the demo.bik file in the program files.
 * The demo contains all of the weapons from the full version. Fuel Rod Canons and Flamethrowers for Multiplayer and Snipers are only in multiplayer. It also contains half of the vehicles of single player, but has a Rocket Warthog and Banshee for multiplayer matters.
