Blaze is a retro/minimalistic styled sci-fi first person flight/shooter action game. The game can be played almost single handedly with just mouse. It's about shooting a lot of alien things (in semi-randomized missions?). The alien things are trying capture all your base, and have already captured at least half of it. You have to defend the base and capture the alien controlled areas back. Or something like that...
Try not to shoot them. Killing/harming them results in minus score/money, more minus if it's you doing it.
The kneeling ones are for hostage rescue missions. The standing/walking/running ones could appear in about any mission. If they get scared they raise their hands up, run erratic or stand paniced.
In hostage rescue missions there should be a timer. After the time has run out, the enemies start killing the hostages. In other missions, enemies kill them randomly, but usually focus on harming player.
