CrystAlien Conflict Version 4.1This version of CrystAlien Conflict was found on 4T2's portfolio minisite for Lego Mars Mission.
It has been reuploaded and archived here for historical reasons.
This version does not have the special ops levels seen in newer versions.
The old version of the alien special ops level seen in newer versions of the game can be played in this version by entering the t2000 cheat code. Note that in place of the alien commander is a normal alien.
To enable test mode in this version, you only need to press 4+2 while in a level, unlike newer versions where a cheat code must be entered first. This page now uses Ruffle to run the game without needing Flash Player.
Ruffle is an in-development Flash Player emulator that may be
used more in the future to preserve legacy Flash content on the web.
