Can anyone recommend games similar to the Sigma shooter games?

I am enjoying the Sigma games because they are very intuitive and simple to interface with. - No complicated ducking, jumping, and other keyboard commands. Just move aim, shoot and explore with your mouse and no need to play online as part of a team.Can anyone recommend other games by other developers similar to these?

Hmmm. Halo spartan assault, though its boring.
I have played some, but i already forgot their names.
The sigma ones are honestly the best of the genre that i recall, no need to change them.

Hello there my friend. So here's what i personaly have on steam:
1) Crimsonland - only survival missions. No walking the laboratories, or else.
2) Gun's'N'Zombies - Almost the same game, but different mechanics and models.
3) I am Weapon: Revival - Second game from the developers of Gun's'N'Zombies
4) Ruiner - No Aliens, but a top-down shooter
5) Splater - Zombiecalypse NOW - This looks like Max Payne & Alien Shooter had a child. Noir Zombie and bugs shooter Top-Down view game.
6) Zombie Driver - a very nice Top-Down view driving game with ARMIES of zombies.
