EVECTOR, Acid Thirst Demo

Some of these guys are located in the area shortly before the boat (teleport here by typing "goto04" in-game). They look like in the achievement icon. Just shoot one and the achievement will pop.

List of cheats (type them while in-game to activate)

• show - toggle hud visibility
• goto0X - go to given checkpoint. uses two digit numbering so type goto01 to go to first checkpoint
• load1X - load given mission. uses two digit numbering so type load12 will load second mission of first episode
• demo0X - load given demo level. uses two digit numbering so type demo01 will load first demo level
• tech0X - load given tech level. uses two digit numbering so type tech01 will load first technical level
• lock - toggle mouse on/off
• navi - toggle navigator ownership
• grnd - toggle grenadier ownership
• heal - give 999 health
• klal - kill all active mobs in level
• ghst - toggle ghost mode. some enemies wont see you until you shoot them

For these achievements, you need to collect a cumulative total of 20 acid crystals. You can type "goto10" once starting a new game, type "heal" for 999 health, turn around and move backwards towards some green crystals to the right, type "klal" to kill the boss and surrounding enemies, then run into these 4 crystals. Die (this will respawn the four crystals), and collect the crystals again over and over until you have the two achievements.
